      Description

      Currently the map task runner creates a thread that calls progress every second to keep the system from killing the map if the sort takes too long. This is the wrong approach, because it will cause stuck tasks to not be killed. The right solution is to have the sort call progress as it actually makes progress. This is part of what is going on in HADOOP-1374. A map gets stuck at 100% progress, but not done.
