What is MapReduce used for?
MapReduce is a programming model that simplifies parallel computing. It gets its name from two key operations, Map and Reduce. Map divides one task into multiple tasks while Reduce summarizes the processing results of these tasks and produces a final analysis result. MapReduce is a distributed data processing mode and execution environment. It provides rapid, massive, parallel data processing.
