Arun Suresh commented on YARN-5185:
-----------------------------------
[~curino], The patch looks pretty straightforward.
Is it possible to add an explicit testcase for this ? or are you saying that
the tests in YARN-5165/YARN-5164 will fail without this ? (in which case don't
you think you should probably merge this with the YARN-5165 patch ?)
