[jira] [Commented] (YARN-5827) DockerLinuxContainer can't limit the cpu usage

    [ https://issues.apache.org/jira/browse/YARN-5827?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15633663#comment-15633663 ] 

Vinod Kumar Vavilapalli commented on YARN-5827:
-----------------------------------------------

Cgroup support is already added via YARN-4553. Can this be closed as dup?

> When I use DockerLinuxContainer, I found that the function of limiting cpu usage doesn't make effect. Because DockerLinuxContainer regard the exitCode of  "docker inpsect" as pid. But When I got this pid, the command of "launch.sh" has started, then we can't add the child process or threads into the cgroup, so the restrictions of cpu usage doesn't make effect。
