---------------------------------------
Hi Sharad,
Thanks for the note. I brought up throwing exception idea (and possibility of
having unchecked exception to prevent changing signature of method) before
Reporter idea came along. Initially people liked Reporter idea better. So let's
say it's open for discussion. Comments/thoughts are welcome.

> Occasionally a mapper/reducer is done without need to see more input data. If
