Vinod Kumar Vavilapalli commented on MAPREDUCE-2986:
----------------------------------------------------
bq. Verified that the patches for MAPREDUCE-3159 and MAPREDUCE-3162 applied on
top of my patch indeed fix the issue with intermittent failure of the tests.
That's great news! So your patch was indeed failing because of existing bugs.
I'll try and move the blocking tickets forward.
Thanks for being on top of this, Anupam!

> The current MiniYARNCluster can only support 1 node manager, which is not
> enough for the full test purposes.
> Would like to have a simulator that can support multiple node managers as the
> real scenario. This might be beneficial for hadoop users, testers and
> developers.
