Modifier and Type	Class and Description
class	MapDriver<K1,V1,K2,V2> Harness that allows you to test a Mapper instance.
class	MapDriverBase<K1,V1,K2,V2,T extends MapDriverBase<K1,V1,K2,V2,T>> Harness that allows you to test a Mapper instance.
class	MapReduceDriver<K1,V1,K2,V2,K3,V3> Harness that allows you to test a Mapper and a Reducer instance together (along with an optional combiner).
class	MapReduceDriverBase<K1,V1,K2,V2,K3,V3,T extends MapReduceDriverBase<K1,V1,K2,V2,K3,V3,T>> 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.
class	MultipleInputsMapReduceDriver<K1,V1,K2,V2> Harness that allows you to test multiple Mappers and a Reducer instance together (along with an optional combiner).
class	PipelineMapReduceDriver<K1,V1,K2,V2> Harness that allows you to test a dataflow through a set of Mappers and Reducers.
class	ReduceDriver<K1,V1,K2,V2> Harness that allows you to test a Reducer instance.
class	ReduceDriverBase<K1,V1,K2,V2,T extends ReduceDriverBase<K1,V1,K2,V2,T>> Harness that allows you to test a Reducer instance.
