After a 1.0 non-root install was upgraded and then the server was rebooted, the following error occurred:

mcsadmin
/home/mariadb-user/mariadb/columnstore/bin/mcsadmin: error while loading shared libraries: libmariadb.so.3: cannot open shared object file: No such file or directory

This is happening because the 1.0 ENV variables aren't cleanly removed as part of the 1.0 install and erase/upgrade process to 1.1.

The main issue is 1.0 postConfigure also calls post-install, which messes up the saved .bashrc file. In 1.1, postConfigure was changed to NOT call post-install, so the problem is not in the 1.1 code.

So a fix in 1.0.12 will need to be done, BUT there might need to be some code or workaround in 1.1 to prevent the problem when user upgrades from 1.0.11 or earlier

-------------------------------------------------------------------------
here is the scenario and why the problem occurred

at 1.0.11 ami launch -

.bashrc

1. MariaDB Columnstore Non-Root Environment Variables
   export COLUMNSTORE_INSTALL_DIR=/home/mariadb-user/mariadb/columnstore
   export LD_LIBRARY_PATH=:/home/mariadb-user/mariadb/columnstore/lib:/home/mariadb-user/mariadb/columnstore/lib:/home/mariadb-user/mariadb/columnstore/mysql/lib/mysql:/home/mariadb-user/mariadb/columnstore/lib:/home/mariadb-user/mariadb/columnstore/lib:/home/mariadb-user/mariadb/columnstore/mysql/lib/mysql

.bashrc.columnstore - is empty

$ cat .bashrc.columnstoreSave

1. .bashrc

1. Source global definitions
   if [ -f /etc/bashrc ]; then
   . /etc/bashrc
   fi

AFTER postConfigure is run:

cat .bashrc.columnstoreSave // has the ENV and alias in there

so when the pre-uninstall is run, the 1.0 ENV and alias will remain.

./mariadb/columnstore/bin/pre-uninstall --installdir=/home/mariadb-user/mariadb/columnstore

cat .bashrc

run postconfigure with new ENV

successfully installs

then reboot
