Wei Yan commented on YARN-2194:
-------------------------------
[~sidharta-s], thanks for the advice. Use a different separator LGTM. In that
way, we can trust the "cpu" controller, and can also help avoid doing
OS-specific changes.
Comments? [~kasha], [~vinodkv], [~mjacobs].
And for the new CGroupsHandlerImpl, didn't find any problem when I checked the
patch. [~vvasudev], please correct me if I missed anything.

> In RHEL7, the CPU controller is named "cpu,cpuacct". The comma in the
> controller name leads to container launch failure.
> RHEL7 deprecates libcgroup and recommends the user of systemd. However,
> systemd has certain shortcomings as identified in this JIRA (see comments).
> This JIRA only fixes the failure, and doesn't try to use systemd.
