Sunil G updated YARN-2113:
--------------------------
Attachment: YARN-2113.v0.patch
Attaching v0 patch for user-limit preemption.
This patch is done on top of YARN-2009 where we have already done intra-queue
preemption framework. This patch focus on adding support to do user-limit
preemption if any is used is under-served, and some other users are abusing the
limit.
Basic test cases are added from preemption module. However I will be adding
some more test cases from scheduler side to ensure that UL computation is also
correct.
[~leftnoteasy] and [~eepayne], please help to share some early feedback.

> 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.
