Subject combiner with GroupComparator
Date Mon, 08 Mar 2010 06:41:40 GMT

I am writing map-reduce program with hadoop-0.20.1, new mapreduce api.

I applied GroupComparator with
job.setGroupingComparatorClass(GroupComparator.class);, but it does
not seem to work in combiner.

If I want to apply GroupingComparator in combiner, what should I do?

Regards Jae
