Using the MapReduce model, obtain the matrix multiplication of A and B. Both matrices are given below. You should use four mappers and two reducers. The different chunks are shown with different colors. Show all the steps of MapReduce to multiply the above matrices including the following: 1. Key-value pairs generated by each mapper? 2. The algorithm used for the map task. 3. A diagram showing how different key-value pairs are shuffled and sorted from mappers to reducers. 4. The output of each reducer and the way it is generated. 5. The algorithm used for the reducer task
