Arun C Murthy updated MAPREDUCE-4327:
-------------------------------------

    Assignee: Arun C Murthy  (was: Andrew Ferguson)
      Status: Open  (was: Patch Available)

Andrew - I think we should break this down into multiple jiras and probably even work on a
branch.

I'll open new jiras and assign some over while I finish up the CS, ok? Thanks.

> With YARN being a general purpose system, it would be useful for several applications
(MPI et al) to specify not just memory but also CPU (cores) for their resource requirements.
Thus, it would be useful to the CapacityScheduler to account for both.
