Subject [jira] [Updated] (YARN-2) Enhance CS to schedule accounting for both memory and cpu cores
Date Thu, 27 Dec 2012 17:02:13 GMT

     [ https://issues.apache.org/jira/browse/YARN-2?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

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

    Attachment: YARN-2.patch

Thanks for catching the bug in CSQueueUtils [~kkambatl], I've fixed computeMaxActiveApplications
to use ResourceCalculator.ratio.

----

I've also added javadocs for ResourceCalculator which should help future maintenance.

----

Overall, I think the patch is ready to go - we can fix naming nits etc. separately - I'm having
a hard time keeping a giant patch up-to-date. 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.
