Hi,
LocalJobRunner uses just 0 or 1 reduce. This is because running in local
mode is only supported for testing purposes.
Although you can simulate distribute mode in local, by using
MiniMRCluster and MiniDFSCluster under src/test.

Hi,
I ran a simple MapReduce job which defines 3 reducers:
*conf.setNumReduceTasks(3);*
When running on top of HDFS (distributed mode), I got 3 out files as I
expected.
When running on top of a local files system (local mode), I got 1 file and
not 3.
My question is whether the behavior in the local is the expected one, is a
bug, or maybe something needs to be configured in the local mode in order to
get the 3 files as well ?
Thanks for an insight, Naama
