Karthik Kambatla commented on YARN-1011:
----------------------------------------
[~elgoiri] - for work that we want to get into trunk/branch-2, I think we
should file separate JIRAs so rest of the community is aware of them. Filed
YARN-4718 for the SchedulerNode changes (and assigned it to you). Filed
YARN-4719 for the helper library. Let us discuss the details in the individual
JIRAs.

> Currently RM allocates containers and assumes resources allocated are
> utilized.
> RM can, and should, get to a point where it measures utilization of allocated
> containers and, if appropriate, allocate more (speculative?) containers.
