Owen O'Malley updated HADOOP-5382:
----------------------------------
Attachment: h5382.patch
This patch pulls the combining functionality into an internal class with two
implementations, one for the old style combiners and one for the new style. Old
and new combiners can mix and match with either new or old applications and
therefore I removed the checks that forced them to be consistent.
> The new map/reduce api doesn't support combiners
