Subject [jira] [Comment Edited] (YARN-2113) Add cross-user preemption within CapacityScheduler's leaf-queue

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

Thank you for all the feedback. We will be considering user-limit as first before priority
when there is a violation.
This patch handles this by default. I have not added any policy for per-priority-userlimit.
We could do that in a separate patch.

Attaching updated patch.

> Preemption today only works across queues and moves around resources across queues per
demand and usage. We should also have user-level preemption within a queue, to balance capacity
across users in a predictable manner.
