Subject [jira] [Commented] (YARN-2194) Add Cgroup support for RedHat 7
Date Thu, 07 May 2015 20:31:01 GMT

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.
