> 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.
