Progress report is not sent during the intermediate sorts in the map phase
--------------------------------------------------------------------------
Key: HADOOP-846
URL: http://issues.apache.org/jira/browse/HADOOP-846
Project: Hadoop
Issue Type: Bug
Components: mapred
Reporter: Devaraj Das
Assigned To: Devaraj Das
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.
