Arun Suresh commented on YARN-1013:
-----------------------------------

Thanks for taking a quick look [~elgoiri]

So, the patch was more of a POC patch (I should have named it as such) I built 
on top of current branch-2 + some YARN-1011 patches I pulled from that branch - 
to vet the approach, but yes, I shall clean it up.. and put in a patch for 
trunk.
