Gergely Pollak commented on YARN-9879:
--------------------------------------
[~wangda], [~prabhujoseph] and [~pbacsko] thank you for your feedback. Latest
patch contains a lot of fixes from Szilard's review, and some serious changes
to CSQueueStore to fix the queue overwrite problem. Also added some tests for
the aforementioned class. I removed the condition which prevented creating
multiple leaf queues with the same name, so I expect some regression, due to
the changes, but I don't expect anything serious. I'll get to implementing
changes suggested in the rest of the reviews, and checking the issues reported
by Prabhu. Hopefully next iteration of the patch will be something very close
to committable material.
