[jira] [Updated] (YARN-2194) Add Cgroup support for RedHat 7

     [ https://issues.apache.org/jira/browse/YARN-2194?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Wei Yan updated YARN-2194:
--------------------------
    Attachment: YARN-2194-2.patch

In Redhat 7, the controller for cpu is "/sys/fs/cgroup/cpu,cpuacct". However, this patch cannot be supported by container-executor due to the comma. So the patch replaces it to "/sys/fs/cgroup/cpu". And "/sys/fs/cgroup/cpu" has already symlinked to "/sys/fs/cgroup/cpu,cpuacct".

>    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.
