Hi Ashish,

Im running the job like this :

mahout matrixmult --inputPathA  --numRowsA <Rowno of MatrixA> --numColsA <C=
olumn 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 <TupleWri=
table> format. Now here Im not sure that what should be the keys  and Value=
<TupleWritable> as Input to mapper to get this job working.=20
