[jira] [Created] (YARN-8929) DefaultOOMHandler should only pick running containers to kill upon oom events

Haibo Chen created YARN-8929:
--------------------------------

             Summary: DefaultOOMHandler should only pick running containers to kill upon oom events
                 Key: YARN-8929
                 URL: https://issues.apache.org/jira/browse/YARN-8929
             Project: Hadoop YARN
          Issue Type: Bug
          Components: nodemanager
    Affects Versions: 3.2.0
            Reporter: Haibo Chen
            Assignee: Haibo Chen


DefaultOOMHandler currently currently sort all known containers based on the execution type primarily and their start time secondarily.

However, it does not check if a container is running or not.  Kill a non-running container will not release any memory, hence won't get us of the under-oom status.
