Vinod Kumar Vavilapalli commented on YARN-2194:
-----------------------------------------------

Also, it will be really useful if we could find a way to support existing code 
on RHEL7, even if libcgroups is deprecated and the approach ends up becoming 
heavy-handed, perhaps with some manual steps. This 
[page|https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/7/html/Resource_Management_Guide/chap-Using_libcgroup_Tools.html]
 talks about ways of doing this.

>    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.
