[jira] [Commented] (YARN-2686) CgroupsLCEResourcesHandler does not support the default Redhat 7/CentOS 7

So YARN-2194 is working on systemd-based solution. Will update a patch for that jira soon.

To avoid conflicts, do not use libcgroup tools for default resource controllers (listed in Available Controllers in Red Hat Enterprise Linux 7) that are now an exclusive domain of systemd. So we plan to move the cpu part using systemd.
