> Components: nodemanager
> Affects Versions: 2.7.0

> 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.
