Subject [jira] [Commented] (YARN-6620) Add support in NodeManager to isolate GPU devices by using CGroups
Date Tue, 24 Oct 2017 00:12:00 GMT

    [ https://issues.apache.org/jira/browse/YARN-6620?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16216105#comment-16216105
] 

Jonathan Hung commented on YARN-6620:
-------------------------------------

I see, thanks [~leftnoteasy], that makes sense.

Seems this is not important for GPU since people will use the GPU plugin for minor numbers
/ GPU isolation (and therefore number of GPUs per node). But this is probably needed for other
resources which don't update via plugin. Created YARN-7383 for this issue.
