Subject [jira] [Commented] (YARN-2194) Add Cgroup support for RedHat 7
Date Thu, 07 May 2015 17:59:01 GMT

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.
