Chris Trezzo commented on YARN-2168:
------------------------------------
Correct. They will be subtasks under YARN-1492. I agree reviewing at the api
level is a good idea. I can re-post the patch with the PB implementation
stripped out, then there will be a smaller patch with a clear view of the api.
