Re: Matrix Multiplication using Hadoop
Hi Shailesh, Please check the implementation. Other than zeros, say there are proper numbers in the input. Is it giving you the right output? Because long back i had taken code from the link which you had mentioned. But for some reason it was not working. Now i have written my own implementation for matrix multiplication on hadoop.

Re: Matrix Multiplication using Hadoop
Hi Naveen, Yes I have checked it with non-zero input matrices, and it works fine. I modified it to support floating point matrices too, and that works well. It doesn't work only when there are zeros in it. If you have you own implementation of matrix multiplication, would you mind sharing it with me? It would be very helpful.

Re: Matrix Multiplication using Hadoop
Hi All, If you have updated matrix multiplication program or any other sample programs for HADOOP, Please share it with me. Thanks in advance for you support.
