Matrix Multiplication on MapReduce

Description

The purpose of this project is to develop a MapReduce program on Hadoop to multiply two

sparse matrices.

Project Description

For this project, you are asked to implement matrix multiplication in Map-Reduce. You should

modify Multiply.java only. In your Java main program, args [0] is the first input matrix M,

args [1] is the second input matrix N, args [2] is the directory name to pass the intermediate

results from the first Map-Reduce job to the second, and args [3] is the output directory. All

the input and output file formats must be text formats. There are two small sparse matrices in

the files M-matrix-small.txt and N-matrix-small.txt for testing in standalone mode. Their

matrix multiplication must return the result matrix in solution-small.txt.
