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

                 Key: HADOOP-755
                 URL: http://issues.apache.org/jira/browse/HADOOP-755
             Project: Hadoop
          Issue Type: Bug
          Components: contrib/streaming
            Reporter: Mahadev konar

A lot of these errors occur in streaming. THis leads to job failure. I still am not sure what
the reason might be of these errors, but these erros occur too often. I will try and invetigate
more to see what the reason might be.
