Subject [jira] Commented: (HADOOP-5223) Refactor reduce shuffle code
Date Wed, 11 Feb 2009 20:02:59 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-5223?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12672749#action_12672749

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).

> 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.
