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

                 Key: HADOOP-2101
                 URL: https://issues.apache.org/jira/browse/HADOOP-2101
             Project: Hadoop
          Issue Type: Bug
          Components: mapred
    Affects Versions: 0.14.3

We have seen one case where JobTracker failed with IOException but later retries of startup
fails with BindException going into loop before failing.
Here is the stacktrace.
