Subject [jira] [Commented] (YARN-3) Add support for CPU isolation/monitoring of containers
Date Wed, 24 Oct 2012 18:54:15 GMT

    [ https://issues.apache.org/jira/browse/YARN-3?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13483467#comment-13483467
] 

Alejandro Abdelnur commented on YARN-3:
---------------------------------------

bq. CgroupsLCEResourcesHandler is swallowing exceptions ....

The user expectation is that if Hadoop is configured to use cgroups, then Hadoop is using
cgroups.

IMO, if we configure Hadoop to use cgroups, and for some reason it cannot, it should be treated
as fatal. 

bq. Make ResourcesHandler top level....

I'd defer this to a follow up patch.
