Karthik Kambatla commented on YARN-2194:
----------------------------------------
RHEL7 recommends using systemd, but doesn't require us to do so. As Wei said,
we thought it might be better to fix the immediate issue (which Wei claims is a
simple fix) instead of switching over to use systemd. We could follow-up with a
fix that uses systemd.

> In previous versions of RedHat, we can build custom cgroup hierarchies
> with use of the cgconfig command from the libcgroup package. From RedHat 7,
> package libcgroup is deprecated and it is not recommended to use it since it
> can easily create conflicts with the default cgroup hierarchy. The systemd is
> provided and recommended for cgroup management. We need to add support for
> this.
