--------------------------------
Summary: RM leaks containers if running container disappears from
node update
Key: YARN-5197
URL: https://issues.apache.org/jira/browse/YARN-5197
Project: Hadoop YARN
Issue Type: Bug
Components: resourcemanager
Affects Versions: 2.6.4, 2.7.2
Reporter: Jason Lowe
Assignee: Jason Lowe
Once a node reports a container running in a status update, the corresponding
RMNodeImpl will track the container in its launchedContainers map. If the node
somehow misses sending the completed container status to the RM and the
container simply disappears from subsequent heartbeats, the container will leak
in launchedContainers forever and the container completion event will not be
sent to the scheduler.
