Devaraj Das commented on HADOOP-5223:
-------------------------------------
This looks nice. 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). Details to follow.
