Eric Payne commented on YARN-2009:
----------------------------------

Hey [~leftnoteasy]. The fate of branch-2.8 is still up in the air, but at this 
point it seems to be leaning towards leaving branch-2.8 as its original branch 
(and not re-branching from head of branch-2). I would like to go ahead and do 
the backport of YARN-4108/YARN-4822 and YARN-4390 to branch-2.8, regardless. 
Any objections?

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