Wangda Tan commented on YARN-2009:
----------------------------------
I suggest to commit this patch first and fix other possible problems separately.
This patch is already very complex and dense, review modified logics is very
painful. Besides user-limit related computations, I don't think it has very
critical issues, many of potential computation mistakes should be able to be
corrected automatically by several rounds of scheduling/preemption logics (Just
like example in the above comment).
Let's focus all the user-limit related issues in the next patch.
Thoughts?

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