The MapReduce framework operates exclusively on pairs, that is, the
framework views the input to the job as a set of pairs and produces a set of pairs
as the output of the job, conceivably of different types. See the flow mentioned below
(input) -> map -> -> combine/sorting -> -> reduce -> (output)
