Class Summary

Class	Description
MapDriver<K1,V1,K2,V2>	Harness that allows you to test a Mapper instance.
MapReduceDriver<K1,V1,K2,V2,K3,V3>	Harness that allows you to test a Mapper and a Reducer instance together You provide the input key and value that should be sent to the Mapper, and outputs you expect to be sent by the Reducer to the collector for those inputs.
MultipleInputsMapReduceDriver<K1,V1,K2,V2>	Harness that allows you to test multiple Mappers and a Reducer instance together (along with an optional combiner).
ReduceDriver<K1,V1,K2,V2>	Harness that allows you to test a Reducer instance.
ReduceFeeder<K,V>	This Class provides some methods to get inputs compatible with new API reducer.
