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

Hi [~eepayne]
Thank you. I guess its more for user fairness based preemption so that if some resource is
grabbed by a user, its to be reclaimed back. Priority is another policy to add in inqueue
preemption. 
I think these policies can be pluggable, and with same framework user can apply these triggers
to achieve use cases. I think along with YARN-4108, inqueue preemption framework can be added
first. And separate triggers (priority, user-limit) can be added as pluggable entities. thoughts?

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