Returns the status of running task.

Interface to implement Combiner for MapReduce.

Assigns a unique Combiner for each provided key.

Allows user to filter the data before providing it to Mapper. Note: if filter is not applied than whole cache data will be mapped.

MapReduce mapper interface generates a set of intermediate key-value pairs for further refining and extraction of the data.

Interface to emit data into more specific and meaningful key-value pair.

Apply aggregation and compilation on final result.

Assigns a unique Reducer for each provided key. Implementing IReducerFactory is optional.

Returns the result of Map Reduce Task result from server.
