Subject [jira] [Commented] (YARN-2440) Cgroups should allow YARN containers to be limited to allocated cores
Date Tue, 26 Aug 2014 09:49:57 GMT

    [ https://issues.apache.org/jira/browse/YARN-2440?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14110556#comment-14110556
] 

Varun Vasudev commented on YARN-2440:
-------------------------------------

[~beckham007] the current implementation of Cgroups uses cpu instead of cpuset, probably due
to the flexibility offered(sharing the cores is handled by the kernel). Is there any particular
benefit to cpuset?

in yarn-site.xml.
