Subject [jira] [Commented] (MAPREDUCE-4327) Enhance CS to schedule accounting for both memory and cpu cores

Andrew Ferguson commented on MAPREDUCE-4327:
--------------------------------------------

hi Arun,

a branch sounds like a great idea. thanks!

I did update the Capacity Scheduler to schedule and account for CPU in the most recent patch.
The key updates are in CSQueueUtils, LeafQueue, and ParentQueue, and they quite heavily tested
by the fully updated Capacity Scheduler test suite.

To update the Capacity Scheduler, I followed the logic from DRF, taking your dominant resource's
share as the capacity you are consuming.


best,
Andrew


ps -- Do you mind if I re-set the Patch Available flag? While this patch passes the tests
I ran locally (`mvn tes`t in hadoop-mapreduce-project/hadoop-yarn/), I am curious what the
Apache buildbot thinks of it. 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.
