Wangda Tan commented on YARN-2009:
----------------------------------
[~eepayne], I'm OK with backport all required patches including
YARN-4108/YARN-4822 and even YARN-4390.
However, there's an ongoing discussion on community about is it better to
re-branch branch-2.8 from branch-2, with that, you don't need all these
backports, will it be an option to you? +[~jlowe].
Thanks,
Wangda

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