postConfigure failed because mysql was still running, so the previous shutdown didnt stop it cleanly. I ran the mysql-Columnstore script and that didnt shut it down and it should have. In the previous version of mysql-Calpont, when it couldnt find the pid file, it would do a kill -9. This code is missing in the mysql-Columnstore script.

root@ip-10-81-19-26:/usr/local/mariadb/columnstore/bin# ../mysql/mysql-Columnstore stop
