             Summary: Support fair scheduler user queue mapping in non-impersonation mode
                 Key: HIVE-8424
                 URL: https://issues.apache.org/jira/browse/HIVE-8424
             Project: Hive
          Issue Type: Improvement
          Components: Shims
            Reporter: Mohit Sabharwal
            Assignee: Mohit Sabharwal


Under non-impersonation mode, all MR jobs will run with identity of hive system user. This
is because 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.
