Increase the buffersize for the streaming parent java process's streams
-----------------------------------------------------------------------

                 Key: HADOOP-3429
                 URL: https://issues.apache.org/jira/browse/HADOOP-3429
             Project: Hadoop Core
          Issue Type: Improvement
            Reporter: Devaraj Das
            Assignee: Amareshwari Sriramadasu
             Fix For: 0.18.0


We saw improved performance when we increased the buffersize for Pipes (HADOOP-1788). In the
streaming case, the buffersize is 8K (default for BufferedOutputStream). We should set that
to 128k.
