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.


> Create a 'ResourceHandler' subsystem to ease addition of support for new 
> resource types on the NM

> 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.
