Thomas Graves created YARN-205:
----------------------------------

             Summary: yarn logs throws nullpointerexception for running application
                 Key: YARN-205
                 URL: https://issues.apache.org/jira/browse/YARN-205
             Project: Hadoop YARN
          Issue Type: Bug
          Components: client
    Affects Versions: 0.23.4
            Reporter: Thomas Graves


I started an application and tried to look at the task logs for the takss that had finished via yarn logs.  Unfortunately it throws a null pointer exception until the job finished:

yarn logs -appOwner tgraves --applicationId application_1352316570518_0002 
Exception in thread "main" java.lang.NullPointerException
