Neelesh Srinivas Salian updated YARN-3996:
------------------------------------------
Attachment: YARN-3996.002.patch
Resolved the issues with the Capacity, FIFO and SLS schedulers.
I am not sure how to approach the testing. Wrote a basic unit test for this at
the moment.
Trying to think how to make it more robust.
Will update if I think of a sturdier approach.
In the meantime, requesting some feedback on version 002 of the patch.
Thank you.
