Devaraj Das updated HADOOP-846:
-------------------------------
Attachment: 846.patch
Attached is the patch - this starts a single thread that does progress
reporting for the entire map phase. Also made taskProgress as volatile since
that is read/updated by multiple threads.
> Progress report is not sent during the intermediate sorts in the map phase

> Have seen tasks getting lost at the TaskTracker's end due to MapTask's
> progress not getting reported for a long time (the configured timeout). The
> progress report is currently not sent in the intermediate sort phases in the
> MapTask. But, if for some reason, the sort takes a long time, the TaskTracker
> might kill the task.
