One other thing that probably should be added is the failure handling (failed-fetch notifications, etc. on getting a CopyResult with an error). > Refactor reduce shuffle code > ---------------------------- > > Key: HADOOP-5223 > URL: https://issues.apache.org/jira/browse/HADOOP-5223 > Project: Hadoop Core > Issue Type: Improvement > Components: mapred > Reporter: Owen O'Malley > Assignee: Owen O'Malley > Fix For: 0.21.0 > > > The reduce shuffle code has become very complex and entangled. I think we should move it out of ReduceTask and into a separate package (org.apache.hadoop.mapred.task.reduce).
