Scott Chen updated MAPREDUCE-220: --------------------------------- Attachment: MAPREDUCE-220-20100806.txt Hey Eli, I think returning a tuple is a very good idea. I updated the patch based on this suggestion. For the sleep time, when I tested it I increase it because I thought I have to wait some time for the update counters. But the counters will be updated at the very beginning of the task. So I changed it back in the patch.
