Subject [jira] [Created] (YARN-6668) Use cgroup to get container resource utilization
Date Tue, 30 May 2017 22:07:04 GMT
Haibo Chen created YARN-6668:
--------------------------------

             Summary: Use cgroup to get container resource utilization
                 Key: YARN-6668
                 URL: https://issues.apache.org/jira/browse/YARN-6668
             Project: Hadoop YARN
          Issue Type: Improvement
          Components: nodemanager
    Affects Versions: 3.0.0-alpha3
            Reporter: Haibo Chen
            Assignee: Haibo Chen


Container Monitor relies on proc file system to get container resource utilization, which
is not as efficient as reading cgroup accounting. We should in NM, when cgroup is enabled,
read cgroup stats instead.
