[jira] [Created] (YARN-324) Provide way to preserve

Lohit Vijayarenu created YARN-324:
-------------------------------------

             Summary: Provide way to preserve 
                 Key: YARN-324
                 URL: https://issues.apache.org/jira/browse/YARN-324
             Project: Hadoop YARN
          Issue Type: Bug
          Components: nodemanager, resourcemanager
    Affects Versions: 2.0.3-alpha
            Reporter: Lohit Vijayarenu


There should be a way to preserve container directories (along with filecache/appcache) for offline debugging. As of today, if container completes (either success or failure) it would get cleaned up. In case of failure it becomes very hard to debug to find out what the case of failure is. Having ability to preserve container directories will enable one to log into the machine and debug further for failures.
