Description
Columstore throws error messages after uninstalling columnstore.
It seems to be searching for the .so files that don't exist post uninstallation.
Things to note:
- Customer is using a non-standard data directory
- Also using different system user & group.
Post installing columnstore, mariadb service runs fine but the error messages in the error log causes their monitoring scripts to raise false alarms.
Installing MariaDB-columnstore-libs MariaDB-columnstore-engine gets rid of the error but customer doesn't want to install unncessary binaries in Production environment.
Installation steps: How customer has installed MariaDB & Columnstore
Tested on 10.4.14-8 version
[root@localhost ~]# ./mariadb_es_repo_setup --token="XXXXXXXXXXXXXXXXXXXXXXX" --apply --mariadb-server-version="10.4.14-8"
[root@localhost ~]# yum install -y MariaDB-server
[root@localhost ~]# yum install -y MariaDB-columnstore-platform.x86_64 MariaDB-columnstore-libs MariaDB-columnstore-engine
[root@localhost ~]# postConfigure
This is the MariaDB ColumnStore System Configuration and Installation tool.It will Configure the MariaDB ColumnStore System and will perform a PackageInstallation of all of the Servers within the System that is being configured.IMPORTANT: This tool requires to run on the Performance Module #1
Prompting instructions:Press 'enter' to accept a value in (), if available or
Enter one of the options within [], if available, or
Enter a new value
===== Setup System Server Type Configuration =====There are 2 options when configuring the System Server Type: single and multi
'single' - Single-Server install is used when there will only be 1 server configured
on the system. It can also be used for production systems, if the plan is
to stay single-server.'multi' - Multi-Server install is used when you want to configure multiple servers now or
in the future. With Multi-Server install, you can still configure just 1 server
now and add on addition servers/modules in the future.Select the type of System Server install [1=single, 2=multi] (2) > 1
Performing the Single Server Install.Enter System Name (columnstore-1) >
===== Setup Storage Configuration =====----- Setup Performance Module DBRoot Data Storage Mount Configuration -----Columnstore supports the following storage options...1 - internal. This uses the linux VFS to access files and does
not manage the filesystem.2 - external *. If you have other mountable filesystems you would
like ColumnStore to use & manage, select this option.
3 - GlusterFS * Note: glusterd service must be running and enabled on
all PMs.4 - S3-compatible cloud storage *. Note: that should be configured
before running postConfigure (see storagemanager.cnf)* - This option enables data replication and server failover in amulti-node configuration.These options are available on this system: [1, 2, 4]
Select the type of data storage (1) >
Enter the list (Nx,Ny,Nz) or range (Nx-Nz) of DBRoot IDs assigned to module 'pm1' (1) >

Columstore throws error messages after uninstalling columnstore.
It seems to be searching for the .so files that don't exist post uninstallation. Things to note: - Customer is using a non-standard data directory - Also using different system user & group. Post installing columnstore, mariadb service runs fine but the error messages in the error log causes their monitoring scripts to raise false alarms. Installing _MariaDB-columnstore-libs MariaDB-columnstore-engine_ gets rid of the error but customer doesn't want to install unncessary binaries in Production environment. h2. Installation steps: How customer has installed MariaDB & Columnstore # {code:java|title=Tested on 10.4.14-8 version} [root@localhost ~]# ./mariadb_es_repo_setup --token="e8499dd2-a9ac-4263-8ac6-cbe1bc0dfb43" --apply --mariadb-server-version="10.4.14-8" [root@localhost ~]# yum install -y MariaDB-server [root@localhost ~]# yum install -y MariaDB-columnstore-platform.x86_64 MariaDB-columnstore-libs MariaDB-columnstore-engine {code} # {code:java} [root@localhost ~]# postConfigure This is the MariaDB ColumnStore System Configuration and Installation tool. It will Configure the MariaDB ColumnStore System and will perform a Package Installation of all of the Servers within the System that is being configured. IMPORTANT: This tool requires to run on the Performance Module #1 Prompting instructions: Press 'enter' to accept a value in (), if available or Enter one of the options within [], if available, or Enter a new value ===== Setup System Server Type Configuration ===== There are 2 options when configuring the System Server Type: single and multi 'single' - Single-Server install is used when there will only be 1 server configured on the system. It can also be used for production systems, if the plan is to stay single-server. 'multi' - Multi-Server install is used when you want to configure multiple servers now or in the future. With Multi-Server install, you can still configure just 1 server now and add on addition servers/modules in the future. Select the type of System Server install [1=single, 2=multi] (2) > 1 Performing the Single Server Install. Enter System Name (columnstore-1) > ===== Setup Storage Configuration ===== ----- Setup Performance Module DBRoot Data Storage Mount Configuration ----- Columnstore supports the following storage options... 1 - internal. This uses the linux VFS to access files and does not manage the filesystem. 2 - external *. If you have other mountable filesystems you would like ColumnStore to use & manage, select this option. 3 - GlusterFS * Note: glusterd service must be running and enabled on all PMs. 4 - S3-compatible cloud storage *. Note: that should be configured before running postConfigure (see storagemanager.cnf) * - This option enables data replication and server failover in a multi-node configuration. These options are available on this system: [1, 2, 4] Select the type of data storage (1) > Enter the list (Nx,Ny,Nz) or range (Nx-Nz) of DBRoot IDs assigned to module 'pm1' (1) > sh: netstat: command not found ===== Performing Configuration Setup and MariaDB ColumnStore Startup ===== NOTE: Setting 'NumBlocksPct' to 50% Setting 'TotalUmMemory' to 25% of total memory.

| Description |
Columstore throws error messages after uninstalling columnstore.
It seems to be searching for the .so files that don't exist post uninstallation. Things to note: - Customer is using a non-standard data directory - Also using different system user & group. Post installing columnstore, mariadb service runs fine but the error messages in the error log causes their monitoring scripts to raise false alarms. Installing _MariaDB-columnstore-libs MariaDB-columnstore-engine_ gets rid of the error but customer doesn't want to install unncessary binaries in Production environment. h2. Installation steps: How customer has installed MariaDB & Columnstore # {code:java|title=Tested on 10.4.14-8 version} [root@localhost ~]# ./mariadb_es_repo_setup --token="e8499dd2-a9ac-4263-8ac6-cbe1bc0dfb43" --apply --mariadb-server-version="10.4.14-8" [root@localhost ~]# yum install -y MariaDB-server [root@localhost ~]# yum install -y MariaDB-columnstore-platform.x86_64 MariaDB-columnstore-libs MariaDB-columnstore-engine {code} # {code:java} [root@localhost ~]# postConfigure This is the MariaDB ColumnStore System Configuration and Installation tool. It will Configure the MariaDB ColumnStore System and will perform a Package Installation of all of the Servers within the System that is being configured. IMPORTANT: This tool requires to run on the Performance Module #1 Prompting instructions: Press 'enter' to accept a value in (), if available or Enter one of the options within [], if available, or Enter a new value ===== Setup System Server Type Configuration ===== There are 2 options when configuring the System Server Type: single and multi 'single' - Single-Server install is used when there will only be 1 server configured on the system. It can also be used for production systems, if the plan is to stay single-server. 'multi' - Multi-Server install is used when you want to configure multiple servers now or in the future. With Multi-Server install, you can still configure just 1 server now and add on addition servers/modules in the future. Select the type of System Server install [1=single, 2=multi] (2) > 1 Performing the Single Server Install. Enter System Name (columnstore-1) > ===== Setup Storage Configuration ===== ----- Setup Performance Module DBRoot Data Storage Mount Configuration ----- Columnstore supports the following storage options... 1 - internal. This uses the linux VFS to access files and does not manage the filesystem. 2 - external *. If you have other mountable filesystems you would like ColumnStore to use & manage, select this option. 3 - GlusterFS * Note: glusterd service must be running and enabled on all PMs. 4 - S3-compatible cloud storage *. Note: that should be configured before running postConfigure (see storagemanager.cnf) * - This option enables data replication and server failover in a multi-node configuration. These options are available on this system: [1, 2, 4] Select the type of data storage (1) > Enter the list (Nx,Ny,Nz) or range (Nx-Nz) of DBRoot IDs assigned to module 'pm1' (1) > sh: netstat: command not found ===== Performing Configuration Setup and MariaDB ColumnStore Startup ===== NOTE: Setting 'NumBlocksPct' to 50% Setting 'TotalUmMemory' to 25% of total memory.

Columstore throws error messages after uninstalling columnstore.
It seems to be searching for the .so files that don't exist post uninstallation. Things to note: - Customer is using a non-standard data directory - Also using different system user & group. Post installing columnstore, mariadb service runs fine but the error messages in the error log causes their monitoring scripts to raise false alarms. Installing _MariaDB-columnstore-libs MariaDB-columnstore-engine_ gets rid of the error but customer doesn't want to install unncessary binaries in Production environment. h2.

It will Configure the MariaDB ColumnStore System and will perform a Package Installation of all of the Servers within the System that is being configured. IMPORTANT: This tool requires to run on the Performance Module #1 Prompting instructions: Press 'enter' to accept a value in (), if available or Enter one of the options within [], if available, or Enter a new value ===== Setup System Server Type Configuration ===== There are 2 options when configuring the System Server Type: single and multi 'single' - Single-Server install is used when there will only be 1 server configured on the system. It can also be used for production systems, if the plan is to stay single-server. 'multi' - Multi-Server install is used when you want to configure multiple servers now or in the future. With Multi-Server install, you can still configure just 1 server now and add on addition servers/modules in the future. Select the type of System Server install [1=single, 2=multi] (2) > 1 Performing the Single Server Install. Enter System Name (columnstore-1) > ===== Setup Storage Configuration ===== ----- Setup Performance Module DBRoot Data Storage Mount Configuration ----- Columnstore supports the following storage options... 1 - internal. This uses the linux VFS to access files and does not manage the filesystem. 2 - external *. If you have other mountable filesystems you would like ColumnStore to use & manage, select this option. 3 - GlusterFS * Note: glusterd service must be running and enabled on all PMs. 4 - S3-compatible cloud storage *. Note: that should be configured before running postConfigure (see storagemanager.cnf) * - This option enables data replication and server failover in a multi-node configuration. These options are available on this system: [1, 2, 4] Select the type of data storage (1) > Enter the list (Nx,Ny,Nz) or range (Nx-Nz) of DBRoot IDs assigned to module 'pm1' (1) > sh: netstat: command not found ===== Performing Configuration Setup and MariaDB ColumnStore Startup ===== NOTE: Setting 'NumBlocksPct' to 50% Setting 'TotalUmMemory' to 25% of total memory.

| Description |
Columstore throws error messages after uninstalling columnstore.
It seems to be searching for the .so files that don't exist post uninstallation. Things to note: - Customer is using a non-standard data directory - Also using different system user & group. Post installing columnstore, mariadb service runs fine but the error messages in the error log causes their monitoring scripts to raise false alarms. Installing _MariaDB-columnstore-libs MariaDB-columnstore-engine_ gets rid of the error but customer doesn't want to install unncessary binaries in Production environment. h2. Installation steps: How customer has installed MariaDB & Columnstore # {code:java|title=Tested on 10.4.14-8 version} [root@localhost ~]# ./mariadb_es_repo_setup --token="e8499dd2-a9ac-4263-8ac6-cbe1bc0dfb43" --apply --mariadb-server-version="10.4.14-8" [root@localhost ~]# yum install -y MariaDB-server [root@localhost ~]# yum install -y MariaDB-columnstore-platform.x86_64 MariaDB-columnstore-libs MariaDB-columnstore-engine {code} # {code:java} [root@localhost ~]# postConfigure This is the MariaDB ColumnStore System Configuration and Installation tool. It will Configure the MariaDB ColumnStore System and will perform a Package Installation of all of the Servers within the System that is being configured. IMPORTANT: This tool requires to run on the Performance Module #1 Prompting instructions: Press 'enter' to accept a value in (), if available or Enter one of the options within [], if available, or Enter a new value ===== Setup System Server Type Configuration ===== There are 2 options when configuring the System Server Type: single and multi 'single' - Single-Server install is used when there will only be 1 server configured on the system. It can also be used for production systems, if the plan is to stay single-server. 'multi' - Multi-Server install is used when you want to configure multiple servers now or in the future. With Multi-Server install, you can still configure just 1 server now and add on addition servers/modules in the future. Select the type of System Server install [1=single, 2=multi] (2) > 1 Performing the Single Server Install. Enter System Name (columnstore-1) > ===== Setup Storage Configuration ===== ----- Setup Performance Module DBRoot Data Storage Mount Configuration ----- Columnstore supports the following storage options... 1 - internal. This uses the linux VFS to access files and does not manage the filesystem. 2 - external *. If you have other mountable filesystems you would like ColumnStore to use & manage, select this option. 3 - GlusterFS * Note: glusterd service must be running and enabled on all PMs. 4 - S3-compatible cloud storage *. Note: that should be configured before running postConfigure (see storagemanager.cnf) * - This option enables data replication and server failover in a multi-node configuration.

Columstore throws error messages after uninstalling columnstore.
It seems to be searching for the .so files that don't exist post uninstallation. Things to note: - Customer is using a non-standard data directory - Also using different system user & group. Post installing columnstore, mariadb service runs fine but the error messages in the error log causes their monitoring scripts to raise false alarms. Installing _MariaDB-columnstore-libs MariaDB-columnstore-engine_ gets rid of the error but customer doesn't want to install unncessary binaries in Production environment. h2. Installation steps: How customer has installed MariaDB & Columnstore # {code:java|title=Tested on 10.4.14-8 version} [root@localhost ~]# ./mariadb_es_repo_setup --token="e8499dd2-a9ac-4263-8ac6-cbe1bc0dfb43" --apply --mariadb-server-version="10.4.14-8" [root@localhost ~]# yum install -y MariaDB-server [root@localhost ~]# yum install -y MariaDB-columnstore-platform.x86_64 MariaDB-columnstore-libs MariaDB-columnstore-engine {code} # {code:java} [root@localhost ~]# postConfigure This is the MariaDB ColumnStore System Configuration and Installation tool.

IMPORTANT: This tool requires to run on the Performance Module #1 Prompting instructions: Press 'enter' to accept a value in (), if available or Enter one of the options within [], if available, or Enter a new value ===== Setup System Server Type Configuration ===== There are 2 options when configuring the System Server Type: single and multi 'single' - Single-Server install is used when there will only be 1 server configured on the system. It can also be used for production systems, if the plan is to stay single-server. 'multi' - Multi-Server install is used when you want to configure multiple servers now or in the future. With Multi-Server install, you can still configure just 1 server now and add on addition servers/modules in the future. Select the type of System Server install [1=single, 2=multi] (2) > 1 Performing the Single Server Install. Enter System Name (columnstore-1) > ===== Setup Storage Configuration ===== ----- Setup Performance Module DBRoot Data Storage Mount Configuration ----- Columnstore supports the following storage options... 1 - internal. This uses the linux VFS to access files and does not manage the filesystem. 2 - external *. If you have other mountable filesystems you would like ColumnStore to use & manage, select this option. 3 - GlusterFS * Note: glusterd service must be running and enabled on all PMs. 4 - S3-compatible cloud storage *. Note: that should be configured before running postConfigure (see storagemanager.cnf) * - This option enables data replication and server failover in a multi-node configuration.

| Description |
Columstore throws error messages after uninstalling columnstore.
It seems to be searching for the .so files that don't exist post uninstallation. Things to note: - Customer is using a non-standard data directory - Also using different system user & group. Post installing columnstore, mariadb service runs fine but the error messages in the error log causes their monitoring scripts to raise false alarms. Installing _MariaDB-columnstore-libs MariaDB-columnstore-engine_ gets rid of the error but customer doesn't want to install unncessary binaries in Production environment. h2. Installation steps: How customer has installed MariaDB & Columnstore # {code:java|title=Tested on 10.4.14-8 version} [root@localhost ~]# ./mariadb_es_repo_setup --token="e8499dd2-a9ac-4263-8ac6-cbe1bc0dfb43" --apply --mariadb-server-version="10.4.14-8" [root@localhost ~]# yum install -y MariaDB-server [root@localhost ~]# yum install -y MariaDB-columnstore-platform.x86_64 MariaDB-columnstore-libs MariaDB-columnstore-engine {code} # {code:java} [root@localhost ~]# postConfigure This is the MariaDB ColumnStore System Configuration and Installation tool. It will Configure the MariaDB ColumnStore System and will perform a Package Installation of all of the Servers within the System that is being configured. IMPORTANT: This tool requires to run on the Performance Module #1 Prompting instructions: Press 'enter' to accept a value in (), if available or Enter one of the options within [], if available, or Enter a new value ===== Setup System Server Type Configuration ===== There are 2 options when configuring the System Server Type: single and multi 'single' - Single-Server install is used when there will only be 1 server configured on the system. It can also be used for production systems, if the plan is to stay single-server. 'multi' - Multi-Server install is used when you want to configure multiple servers now or in the future. With Multi-Server install, you can still configure just 1 server now and add on addition servers/modules in the future. Select the type of System Server install [1=single, 2=multi] (2) > 1 Performing the Single Server Install. Enter System Name (columnstore-1) > ===== Setup Storage Configuration ===== ----- Setup Performance Module DBRoot Data Storage Mount Configuration ----- Columnstore supports the following storage options... 1 - internal. This uses the linux VFS to access files and does not manage the filesystem. 2 - external *. If you have other mountable filesystems you would like ColumnStore to use & manage, select this option. 3 - GlusterFS * Note: glusterd service must be running and enabled on all PMs. 4 - S3-compatible cloud storage *. Note: that should be configured before running postConfigure (see storagemanager.cnf) * - This option enables data replication and server failover in a multi-node configuration.

Columstore throws error messages after uninstalling columnstore.
It seems to be searching for the .so files that don't exist post uninstallation. Things to note: - Customer is using a non-standard data directory - Also using different system user & group. Post installing columnstore, mariadb service runs fine but the error messages in the error log causes their monitoring scripts to raise false alarms. Installing _MariaDB-columnstore-libs MariaDB-columnstore-engine_ gets rid of the error but customer doesn't want to install unncessary binaries in Production environment. h2. Installation steps: How customer has installed MariaDB & Columnstore # {code:java|title=Tested on 10.4.14-8 version} [root@localhost ~]# ./mariadb_es_repo_setup --token="e8499dd2-a9ac-4263-8ac6-cbe1bc0dfb43" --apply --mariadb-server-version="10.4.14-8" [root@localhost ~]# yum install -y MariaDB-server [root@localhost ~]# yum install -y MariaDB-columnstore-platform.x86_64 MariaDB-columnstore-libs MariaDB-columnstore-engine {code} # {code:java} [root@localhost ~]# postConfigure This is the MariaDB ColumnStore System Configuration and Installation tool.

IMPORTANT: This tool requires to run on the Performance Module #1 Prompting instructions: Press 'enter' to accept a value in (), if available or Enter one of the options within [], if available, or Enter a new value ===== Setup System Server Type Configuration ===== There are 2 options when configuring the System Server Type: single and multi 'single' - Single-Server install is used when there will only be 1 server configured on the system. It can also be used for production systems, if the plan is to stay single-server. 'multi' - Multi-Server install is used when you want to configure multiple servers now or in the future. With Multi-Server install, you can still configure just 1 server now and add on addition servers/modules in the future. Select the type of System Server install [1=single, 2=multi] (2) > 1 Performing the Single Server Install. Enter System Name (columnstore-1) > ===== Setup Storage Configuration ===== ----- Setup Performance Module DBRoot Data Storage Mount Configuration ----- Columnstore supports the following storage options... 1 - internal. This uses the linux VFS to access files and does not manage the filesystem. 2 - external *. If you have other mountable filesystems you would like ColumnStore to use & manage, select this option. 3 - GlusterFS * Note: glusterd service must be running and enabled on all PMs. 4 - S3-compatible cloud storage *. Note: that should be configured before running postConfigure (see storagemanager.cnf) * - This option enables data replication and server failover in a multi-node configuration.

Columstore throws error messages after uninstalling columnstore.
It seems to be searching for the .so files that don't exist post uninstallation. Things to note: - Customer is using a non-standard data directory - Also using different system user & group. Post installing columnstore, mariadb service runs fine but the error messages in the error log causes their monitoring scripts to raise false alarms. Installing _MariaDB-columnstore-libs MariaDB-columnstore-engine_ gets rid of the error but customer doesn't want to install unncessary binaries in Production environment. h2. Installation steps: How customer has installed MariaDB & Columnstore # {code:java|title=Tested on 10.4.14-8 version} [root@localhost ~]# ./mariadb_es_repo_setup --token="e8499dd2-a9ac-4263-8ac6-cbe1bc0dfb43" --apply --mariadb-server-version="10.4.14-8" [root@localhost ~]# yum install -y MariaDB-server [root@localhost ~]# yum install -y MariaDB-columnstore-platform.x86_64 MariaDB-columnstore-libs MariaDB-columnstore-engine {code} # {code:java} [root@localhost ~]# postConfigure This is the MariaDB ColumnStore System Configuration and Installation tool. It will Configure the MariaDB ColumnStore System and will perform a Package Installation of all of the Servers within the System that is being configured. IMPORTANT: This tool requires to run on the Performance Module #1 Prompting instructions: Press 'enter' to accept a value in (), if available or Enter one of the options within [], if available, or Enter a new value ===== Setup System Server Type Configuration ===== There are 2 options when configuring the System Server Type: single and multi 'single' - Single-Server install is used when there will only be 1 server configured on the system. It can also be used for production systems, if the plan is to stay single-server. 'multi' - Multi-Server install is used when you want to configure multiple servers now or in the future. With Multi-Server install, you can still configure just 1 server now and add on addition servers/modules in the future. Select the type of System Server install [1=single, 2=multi] (2) > 1 Performing the Single Server Install. Enter System Name (columnstore-1) > ===== Setup Storage Configuration ===== ----- Setup Performance Module DBRoot Data Storage Mount Configuration ----- Columnstore supports the following storage options... 1 - internal. This uses the linux VFS to access files and does not manage the filesystem. 2 - external *. If you have other mountable filesystems you would like ColumnStore to use & manage, select this option. 3 - GlusterFS * Note: glusterd service must be running and enabled on all PMs. 4 - S3-compatible cloud storage *. Note: that should be configured before running postConfigure (see storagemanager.cnf) * - This option enables data replication and server failover in a multi-node configuration.

Columstore throws error messages after uninstalling columnstore.
It seems to be searching for the .so files that don't exist post uninstallation. Things to note: - Customer is using a non-standard data directory - Also using different system user & group. Post installing columnstore, mariadb service runs fine but the error messages in the error log causes their monitoring scripts to raise false alarms. Installing _MariaDB-columnstore-libs MariaDB-columnstore-engine_ gets rid of the error but customer doesn't want to install unncessary binaries in Production environment. h2. Installation steps: How customer has installed MariaDB & Columnstore # {code:java|title=Tested on 10.4.14-8 version} [root@localhost ~]# ./mariadb_es_repo_setup --token="XXXXXXXXXXXXXXXXXXXXXXX" --apply --mariadb-server-version="10.4.14-8" [root@localhost ~]# yum install -y MariaDB-server [root@localhost ~]# yum install -y MariaDB-columnstore-platform.x86_64 MariaDB-columnstore-libs MariaDB-columnstore-engine {code} # {code:java} [root@localhost ~]# postConfigure This is the MariaDB ColumnStore System Configuration and Installation tool. It will Configure the MariaDB ColumnStore System and will perform a Package Installation of all of the Servers within the System that is being configured. IMPORTANT: This tool requires to run on the Performance Module #1 Prompting instructions: Press 'enter' to accept a value in (), if available or Enter one of the options within [], if available, or Enter a new value ===== Setup System Server Type Configuration ===== There are 2 options when configuring the System Server Type: single and multi 'single' - Single-Server install is used when there will only be 1 server configured on the system. It can also be used for production systems, if the plan is to stay single-server. 'multi' - Multi-Server install is used when you want to configure multiple servers now or in the future. With Multi-Server install, you can still configure just 1 server now and add on addition servers/modules in the future. Select the type of System Server install [1=single, 2=multi] (2) > 1 Performing the Single Server Install. Enter System Name (columnstore-1) > ===== Setup Storage Configuration ===== ----- Setup Performance Module DBRoot Data Storage Mount Configuration ----- Columnstore supports the following storage options... 1 - internal. This uses the linux VFS to access files and does not manage the filesystem. 2 - external *. If you have other mountable filesystems you would like ColumnStore to use & manage, select this option. 3 - GlusterFS * Note: glusterd service must be running and enabled on all PMs. 4 - S3-compatible cloud storage *. Note: that should be configured before running postConfigure (see storagemanager.cnf) * - This option enables data replication and server failover in a multi-node configuration.

Found the resolution.
This can be closed.
The error was duee to columnstore remains in the following system table mysql.func.
Once the table is truncated and mariadb is restarted, the error no longer pops up.

Build tested: 6.4.1-1 (#4661)
Release 1.4.4 is a very old version. Installation method has been improved in the current release. The mcsadmin tool is no longer available.
Test scenario:
1. query mysql.func table
2. stop mariadb mariadb-columnstore
3. rpm -e ColumnStore RPM package
4. start mariadb
After installation, the mysql.func table has 49 rows.
1. In VM
After uninstalling ColumnStore and starting MariaDB, mysql.func still has 49 rows. Any time MariaDB is started, the /var/log/messages file contains the report error messages.
After truncating mysql.func, restarting MariaDB no longer causing the reported errors.
2. In docker container
After uninstalling ColumnStore and starting MariaDB, mysql.func has 0 rows. /var/log/messages did not have the reported errors.
