----------------------------------

Integrated in Hadoop-Common-trunk-Commit #8 (See [http://hudson.zones.apache.org/hudson/job/Hadoop-Common-trunk-Commit/8/])

> 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.
