This is the first lab of MIT 6.824, Distributed Systems. It is about the implementation of MapReduce, a framework introduced by Google that can process huge volume of data parallelly by splitting a single task to multiple small ones and assigning them to a cluster of “cheap” machines. And by using this framework, also as mentioned in the paper, this lets programmer make use of distributed system without the need of experience of it.

A very classic use case of this framework is counting words in a large file, which is also what we are to implement.
