    Description

      MCS itself is perfectly fine running w/o root privileges except a couple of things:
      ExeMgr, WriteEngine and PrimProc raise a number of open file descriptors so systemd units must contain LimitNOFILE=65536.
      There are a number of directories that must have appropriate access modes and owners. Here is the list of related commands I run to get MCS working under an arbitrary user.

      chown -R mcs /var/log/mariadb/columnstore/
      		 
      chown -R mcs /etc/columnstore/
      		 
      chown -R mcs /var/lib/columnstore/
      		 
      chown -R mcs /tmp/columnstore_tmp_files/
      		 
      chmod 764 /tmp/columnstore_tmp_files/

      There is a relevant article on installing MCS under non-root user.

      The upgrade from 1.2/4 to 1.5 must be tested.
