Exercises in MapReduce Style

This is the 19th post in the Exercises in Programming Style focus series. In the last episode of Exercises in Programming Style, we solved the word frequency problem with the Hazelcast library. This time, we are going to use MapReduce for that. MapReduce is a process consisting of two steps: Map performs transformations, filtering and sorting into different queues. Reduce aggregates the content of the queues into a result.
