-------------------------------------------------------------------------------------------

                 Key: HADOOP-1502
                 URL: https://issues.apache.org/jira/browse/HADOOP-1502

            Reporter: Koji Noguchi
            Priority: Minor
             Fix For: 0.12.3


When tasks started up on a brand new mapred cluster, I saw couples of them fail immediately
 by
