Sunil G commented on YARN-2009:
-------------------------------
Thanks [~leftnoteasy] for sharing the updates. I will also take a look on
YARN-4108.
bq.I think how to choose to-be preempted containers should be handled inside
PCPP by different policies
At first step, this will be really helpful and it will make code more easier
and understandable. For in queue preemption, I will work on a similar approach
what is taken in PCPP and will post a doc here. I think it can be another
policy which is independent of PCPP, but could share few common code as
possible.

> While preempting containers based on the queue ideal assignment, we may need
> to consider preempting the low priority application containers first.
