Daniel Templeton updated YARN-4143:
-----------------------------------
Attachment: YARN-4143.002.patch
Since [~adhoot] doesn't seem to be working on this one anymore, I just rebased
it and posted a new patch. This patch turns out to be considerably simpler
than its predecessor because some of the cleanup that was in the original patch
made it in already. [~sunilg], wanna have a look?
> Optimize the check for AMContainer allocation needed by blacklisting and
> ContainerType
