Eric Payne updated YARN-2056:

    Attachment: YARN-2056.201410232244.txt

Thanks very much [~leftnoteasy]. I have attached a patch which uses PriorityQueue instead
of an internal queue class.

Please note that since the algorithm for building up needy queues is different, the rounding
is also different, so some of the tests' expected values needed to change. I stepped through
several of the tests and they seem to be working as I expect.
