Devaraj Das updated HADOOP-1485:
--------------------------------

    Attachment: 1485.1.patch

Attached is a more patch with a more detailed metrics reporting. I am still testing this but I would appreciate reviews on the same, especially on the lines of reporting metrics that would help us monitor the shuffle better.

> It would be nice to have metrics for the shuffle phase which reports the failures/successes for the fetches. This would aid in performance tests and in debugging (shuffle).
