Arun C Murthy updated YARN-2:
-----------------------------

    Attachment: YARN-2.patch

Thanks for the fix Junping, I've incorporated it.

The latest patch looks good to go, all unit tests work and I've run sample jobs on a real
cluster.

Can anyone pls take a look? Tx.

> 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.
