"Book serial" MapReduce is a kind of programming model that can be used in data processing. The model is simple, but it is not easy to write useful programs. Hadoop can run MapReduce programs written in various languages. In this chapter, we'll see the same program written in Java, Ruby, Python, and C + + languages. Most importantly, the MapReduce program is essentially running in parallel, so large data analysis tasks can be delegated to any operator with enough machines. MapReduce ...
