Subject [jira] Updated: (HADOOP-613) The final merge on the reduces should feed the reduce directly
Date Sat, 11 Nov 2006 06:16:39 GMT
     [ 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 input to the reduce should use the iterators from HADOOP-611 directly
rather than using a round trip to disk.
