combiner without reducer
Radim Kolar 2013-04-15, 17:37
i have need for running combiner without reducers.

Workflow mapper -> sort -> combiner -> hdfs.

do you think that you will ever support that scenario? Its quite common
because few hadoop frameworks supports it, but they emulate it in mapper
by caching results into memory.
