[ http://issues.apache.org/jira/browse/HADOOP-613?page=all ]
Devaraj Das updated HADOOP-613:
-------------------------------
Attachment: reduce-get-iterator.patch
This has a bugfix to do with progress reporting (discovered during the run of
the sort benchmark). Stating the obvious - the sort benchmark should get a good
performance boost with this patch. Could someone please review this?
> The final merge on the reduces should feed the reduce directly
