----------------------------------

             Summary: Expose demand at the queue level for FairScheduler
                 Key: YARN-5056
                 URL: https://issues.apache.org/jira/browse/YARN-5056
             Project: Hadoop YARN
          Issue Type: Improvement
    Affects Versions: 2.7.2
            Reporter: Daniel Weeks
            Priority: Minor


There currently isn't a way to determine where demand is coming from within the scheduler.  Issues like YARN-2408 proposed a more detailed way to expose this information, but it's very easy to expose this at a queue level by simply including the queue demand, which is a good indicator of where resources requests are coming from (at least at the queue level).

This will help to better understand metrics like "containersPending" and where resource requests are originating.
