Subject [jira] [Commented] (YARN-2194) Add Cgroup support for RedHat 7
Date Thu, 22 Jan 2015 14:02:35 GMT

Karthik Kambatla commented on YARN-2194:
----------------------------------------

container-executor.c - the new method significantly duplicates the existing one. Can we have
separate methods to capture the differences and leave the original method as is.

>    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.
