Subject [jira] Created: (HADOOP-1488) Remove all use of auto-progress threads in map/reduce
Date Wed, 13 Jun 2007 17:14:25 GMT
Remove all use of auto-progress threads in map/reduce
-----------------------------------------------------

                 Key: HADOOP-1488
                 URL: https://issues.apache.org/jira/browse/HADOOP-1488
             Project: Hadoop
          Issue Type: Bug
          Components: mapred
            Reporter: Owen O'Malley


During the last rework of the shuffle, a lot of the stages of the shuffle had auto-progress
threads added, leading to system lockups when the shuffle stalls. We need to add Progressables
to the sort and fetching interfaces so that if any task gets stuck, it will eventually be
killed by the framework.
