[~ananyo_rao] since this is pending for a while now and the patch doesn't apply to trunk anymore, do you plan to update it? If not, would you mind if I take over the task of managing/updating it?

> Usecase:
> Due to the way Capacity Scheduler preemption works, If a single user submits a large application to a queue (using 100% of resources), that job will not be preempted by future applications from the same user within the same queue. This implies that the later applications will be forced to wait for completion of the long running application. This prevents multiple long running, large, applications from running concurrently.
> Support fair sharing among apps while preempting applications from same queue.
