Hi Ashish, I tried to run the "matrixmult" example of Mahout but getting errors in input format. I want to create the input file of matrix in the format which is required by MatrixMultiplicationJob for further processing. Im facing issues in creating that file as I have doubts that what will be the key and values for the input file. Anybody's help will be appreciated.
