Subject [jira] [Created] (YARN-139) Interrupted Exception within AsyncDispatcher leads to user confusion
Date Mon, 01 Oct 2012 19:53:07 GMT
Nathan Roberts created YARN-139:
-----------------------------------

             Summary: Interrupted Exception within AsyncDispatcher leads to user confusion
                 Key: YARN-139
                 URL: https://issues.apache.org/jira/browse/YARN-139
             Project: Hadoop YARN
          Issue Type: Bug
          Components: api
    Affects Versions: 2.0.2-alpha, 0.23.4
            Reporter: Nathan Roberts


Successful applications tend to get InterruptedExceptions during shutdown. The exception is
harmless but it leads to lots of user confusion and therefore could be cleaned up.
