> 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.
