> 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.
