[jira] [Created] (YARN-438) NM on startup should handle cleaning up of any running containers managed by the previous instance

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.
