 Description   

I've had this reported from several community members and have been able to reproduce myself. On a single-server Ubuntu 16.04 setup the ColumnStore logs are going into the system journal instead of the files in /usr/local/mariadb/columnstore.

I believe the reason is during postConfigure syslog is restarted several times rapidly. Ubuntu's systemd says this is happening too often and we end up with syslog not starting at all. The log data then falls back to the system journal.

I of course mean it isn't going into /var/log/mariadb/columnstore (typed /usr/local from muscle memory it seems)

found that is restarted 3 times just in the post-install running process. This is all being done in syslogSetup.sh... So this script needs to be changed to add more logic to to have it restart multiple times. will check other area in the code at startup.

/bin/syslogSetup.sh install also called by postCOnfigure. It doesnt need to be called here since its called in post-install. so will remove it from postConfigure.

fixed in 1.0.10 first, tweaked post-install, postConfigure, and syslogSetup.sh.
Changes went from having the service called 6 times down to 1 time during a install and upgrade install.

how I tested on ubuntu 16.04

1. in one window, do the following:

  1. cd /var/log
  2. tailf syslog | grep "Starting System Logging Service"
    2. in another window, do binary installs
  3. ./post-install
  4. ./postConfigure

simulate an upgrade install

  1. ./pre-uninstall
  2. ./post-install
  3. ./postConfigure

Before change you would see 4 to 6 logs to start rsyslog, now should just see 1

Build verified: 1.0.10-1

logs are going into both syslog and columnstore log files.
