Alejandro Abdelnur commented on YARN-392:
-----------------------------------------
Agree with Sandy, the low level API contract requires deep understanding of how
things work, the AMRMClient layer hides/handles much of that complexity
already, this particular feature should be handle there in the similar way.
[~sandyr] please open a JIRA for it.
> Make it possible to schedule to specific nodes without dropping locality

> assigns non-specified machines to the app.
