-------------------------------
Possibly by moving the imports into an inner class, which is only loaded if
{{isFairScheduler(conf) == true}}
> Support fair scheduler user queue mapping in non-impersonation mode

> 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.
