Subject [jira] [Commented] (YARN-2194) Add Cgroup support for RedHat 7
Date Wed, 02 Jul 2014 04:00:26 GMT

    [ https://issues.apache.org/jira/browse/YARN-2194?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14049593#comment-14049593

Beckham007 commented on YARN-2194:
----------------------------------

+1.
A new LCEResourceHandler is needed. To support more resource isolation, we also need to have
init(), preExecute() and postExecute() for different resource. Adding an abstract CgroupsResourceManager
and its implement CPUResourceManager\MemResourceManager is good.

> 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.
