    • Adds Reduce Attempt ID to ClientTrace log messages, and adds Reduce Attempt ID to HTTP query string sent to mapOutputServlet. Extracts partition number from attempt ID.

    Description

      Current clienttrace messages from shuffles note only the destination map ID but not the source reduce ID. Having both source and destination ID of each shuffle enables full tracing of execution.
