    • Increased the size of the buffer used in the communication between the Java task and the Streaming process to 128KB.

    Description

      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.
