Subject [jira] [Commented] (YARN-3443) Create a 'ResourceHandler' subsystem to ease addition of support for new resource types on the NM
Date Tue, 07 Apr 2015 05:00:16 GMT

    [ https://issues.apache.org/jira/browse/YARN-3443?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14482591#comment-14482591

Varun Vasudev commented on YARN-3443:
-------------------------------------

Minor documentation fixes, everything else looks good.

# In PrivilegedOperationExecutor.java, getPrivilegedOperationExecutionCommand is documented
as throwing ExitCodeException but it doesn't throw it.
# In CGroupsHandler.java, the documentation for createCGroup is missing descriptions for controller
and path.

> The current cgroups implementation is closely tied to supporting CPU as a resource .
We need to separate out CGroups support as well a provide a simple ResourceHandler subsystem
that will enable us to add support for new resource types on the NM - e.g Network, Disk etc.
