 Description   

Per dshjoshi's email today:
.. binaries for CentOS 7, Debian 8 and Ubuntu 16.04 binaries on Portal ...

These platforms are 'systemd' platforms. The existing scripts for InfiniDB are all init.d based. systemd based services will have to be created for the new operating systems that use 'systemd'.

how to test.

on centos 6
----------------

after install:

  1. chkconfig --list | grep columnstore // you should see
    columnstore 0:off 1:off 2:on 3:on 4:on 5: on 6:off

reboot node and make sure columnstore is automatically restarted

after uninstall, if you run the same command it will show nothing

on centos 7
---------------

after install:

  1. sysyemctl list-unit-files | grep columnstore // you should see
    columnstore enabled

reboot node and make sure columnstore is automatically restarted

Merge branch 'develop' into MCOL-70

NOTE: I didn't use the exact systemd service script from the example you provided. The main issues is the old 'columnstore' script does extra setup for non-root and hdfs. That is where I had the issue of trying to figure out how to do that in the new systemd script. So all I ended up doing is creating a new systemd script, columnstore.service, that just called the old script, columnstore, so we have the some functionality.

ExecStopPost could be replaced with ExecStop because ExecStopPost is run only after SIGTERM is sent to the process. With ExecStop, /usr/local/mariadb/columnstore/bin/columnstore stop is the only command executed.

For details, see systemd.service(5).
