Daniel Templeton commented on YARN-6166:
----------------------------------------

LGTM.  +1

Next, time, though, it's better to keep all the patches attached to the JIRA so that the history is preserved.  To avoid confusion, we usually name them YARN-6166.001.patch, YARN-6166.002.patch, etc.

I'll commit it in a bit.
