Hi Ashish, Im running the job like this :
mahout matrixmult --inputPathA --numRowsA <Rowno of MatrixA> --numColsA <Column no of MatrixA> --inputPathB <Inputpath of MatrixB> --numRowsB <Rowno of MatrixB> --numColsB <Column no of MatrixB> --tempDir <temporaryDir path> And getting the errors of InputFormat in mapper as mapper expects <TupleWritable> format. Now here Im not sure that what should be the keys and Value<TupleWritable> as Input to mapper to get this job working. -Stuti -----Original Message----- From: ashish negi [mailto:[email protected]] Sent: Monday, January 14, 2013 2:29 PM To: [email protected] Subject: Re: MatrixMultiplicationJob Input query Could you tell how are you trying to run the job?
