The partitioner class can be used to achieve this. (http://hadoop.apache.org/mapreduce/docs/r0.21.0/api/org/apache/hadoop/mapreduce/Partitioner.html).

Is there anyway to influence where a reduce task is run? We have a case where we'd like to choose the host to run the reduce task based on the task's input key.
Any suggestion is greatly appreciated.
