Lefty Leverenz commented on HIVE-8424:
--------------------------------------
Here's a hybrid description of *hive.server2.map.fair.scheduler.queue* for your
consideration:
{quote}
If the YARN fair scheduler is configured and HiveServer2 is running in
non-impersonation mode, this determines the user for fair scheduler queue
mapping. If set to true (default) the logged-in user determines the fair
scheduler queue for submitted jobs, so that MR resource usage can be tracked by
user. If set to false, all Hive jobs go to the 'hive' user's queue.

> Under non-impersonation mode, all MR jobs run as the hive system user. The
> default scheduler queue mapping is one queue per user. This is problematic
> for users who use the queues to regulate and track their MR resource usage.
> Yarn exposes an API to retrieve the fair scheduler queue mapping, which we
> can use to set the appropriate MR queue for the current user.
