Subject [jira] [Commented] (YARN-2440) Cgroups should limit YARN containers to cores allocated in yarn-site.xml
Date Fri, 22 Aug 2014 17:34:12 GMT

    [ https://issues.apache.org/jira/browse/YARN-2440?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14107141#comment-14107141
] 

Jason Lowe commented on YARN-2440:
----------------------------------

Interesting.  [~sandyr] could you comment?  I'm wondering how we're going to support automatically
setting a node's vcore value based on the node's physical characteristics without some kind
of property to specify how to convert from physical core to vcore.
