Description
Customer request:
If the OS flushes /tmp on reboot, Have the installer setup the proper tempfiles.d so the directory gets created when the system starts, to ensure the functions that use /tmp/<blah> will work when ColumnStore tries to use them.
An alternate method of having ColumnStore create the dir if it does not exist may not be sufficient as privileges must be granted for programs to be run by other than root.
Also add to docs that if running programs as other than root, one may need to add an entry to /etc/tempfiles.d/ to get the directory created with proper permissions for that user to successfully execute colxml, cpimport, etc..
Since you do not know what user a customer may run such programs as, this will likely continue to be a problem in the future.

For RPM/DEB that would be easy during the postinst script. For non-root we would probably use /usr/local/mariadb/columnstore/tmp or something like that.
"columnstore start" already creates the temp dir which is in the SystemTempFileDir value in the config file. This is /tmp/columnstore_tmp_files for root user and $HOME/.tmp for non-root user.
The issue isnt that the tmp directories arent being created, its that the tmp directory for root user is only writeable by root user. Customer is running some commands as non-root user, which is allowed, and the nonroot user is getting an error writing into the root user install /tmp area. The BUG request to to setup /tmp for columnstore to allow all users to write to it.

Merge pull request #1113 from pleblanc1976/develop-1.4
Bumped version num to 1.4.4-1
Would not startup code need root access to create the tmp dir on some machines?
