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

zhengchenyu created YARN-5827:
---------------------------------

             Summary: DockerLinuxContainer can't limit the cpu usage
                 Key: YARN-5827
                 URL: https://issues.apache.org/jira/browse/YARN-5827
             Project: Hadoop YARN
          Issue Type: Bug
          Components: nodemanager
    Affects Versions: 2.8.0
         Environment: CentOS7.1
            Reporter: zhengchenyu
             Fix For: 2.8.0


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。
