Hitesh Shah created YARN-438:
--------------------------------
Summary: NM on startup should handle cleaning up of any running
containers managed by the previous instance
Key: YARN-438
URL: https://issues.apache.org/jira/browse/YARN-438
Project: Hadoop YARN
Issue Type: Bug
Reporter: Hitesh Shah
Priority: Critical
If the NM is shutdown in a non-clean manner, the containers launched by it will
remain running. When a NM is brought up, there needs to be some handling to
ensure that the node is clean before new containers can be launched on it.
Special care should be taken to handle cases where the PIDs wrap around - it
may be non-trivial to figure out if the process running currently actually maps
to the previously launched container.
