MapReduce is a type of programming model which is used for processing and generating big data sets, with a parallel and distributed algorithm on a cluster.
MapReduce is used to process huge amounts of data, which in itself is a software framework and is a programming model. MapReduce programs are parallel in nature and that aids in effectively analyzing large-scale data with the help of multiple machines in the cluster.
MapReduce is in effect 2 programs in one, Map handles the mapping and splitting of data while Reduce is tasked with shuffling and reducing the data.
