---------------------------------
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。
