      HIVE-677 . Operators to show number of rows forwarded. (Namit Jain via zshao)

      Description

      Currently, we have no idea how many rows are being produced by join/file sink while the process is running.
      It makes the tasks very difficult to debug - it would be very useful to dump some stats while the process (mapper/reducer) is running
