--------------------------------
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.
