Phabricator commented on HIVE-2931:
-----------------------------------

stuart983 has commented on the revision "HIVE-2931 [jira] conf settings may be 
ignored".

  One thing I just don't understand is, if always doing db.conf= c works, then 
why we need to comparing the meta vars and only modify when there is 
difference? I think we must have missed something here.

> This is a pretty serious problem.
> If a conf variable is changed, Hive may not pick up the variable unless the 
> metastore variables are changed.
> When any session variables are changed, it might be simpler to update the 
> corresponding Hive conf.
