Subject [jira] [Created] (YARN-8461) Support strict memory control on individual container with elastic control memory mechanism
Date Tue, 26 Jun 2018 00:00:33 GMT
Haibo Chen created YARN-8461:
--------------------------------

             Summary: Support strict memory control on individual container with elastic control
memory mechanism
                 Key: YARN-8461
                 URL: https://issues.apache.org/jira/browse/YARN-8461
             Project: Hadoop YARN
          Issue Type: Improvement
          Components: nodemanager
    Affects Versions: 3.2.0
            Reporter: Haibo Chen
            Assignee: Haibo Chen


YARN-4599 adds elastic memory control that disables oom killer for the root container cgroup.
Hence, all containers have their oom killer disabled because they inherit the setting from
the root container cgroup. Hence, when strict memory control on individual containers is also
enabled, the container will be frozen but not killed. We can let the container monitoring
thread to take care of the frozen containers.
