Write a MapReduce program in Hadoop that implements the single-path Matrix Multiplication. a= 1 2 3 4 5 66 76 68 9 10 11 12 b= 5 4 3 2 1 7 22 91 54 6 9 11 1 2 3 4 the Map function will produce its key,value pairs from the input data and the Reduce function uses the output of the Map function, performs the calculations, and produces its key,value pairs.
