Varun Vasudev updated YARN-3542:
--------------------------------
    Attachment: YARN-3542.006.patch

bq. Adding a @Deprecated to TestCgroupsLCEResourcesHandler would remove the 
deprecated warning use - this test class should be deprecated anyway?

Yep. Fixed.

bq. Some checkstyle comments need looking into (line lengths for new code, 
mostly)

Fixed as many as I could - the rest are package lines and one config variable.

> In YARN-3443 , a new ResourceHandler mechanism was added which enabled easier 
> addition of new resource types in the nodemanager (this was used for network 
> as a resource - See YARN-2140 ). We should refactor the existing CPU 
> implementation ( LinuxContainerExecutor/CgroupsLCEResourcesHandler ) using 
> the new ResourceHandler mechanism.
