Hi Edward, I cannot run the program from the debug mode. As I told you previously I get Java Heap space exception.
I am able to print the matrices that I have. The matrices are as under. Is it possible that the map reduce progress is getting blocked because of the kind of numbers being stored in the matrices. Matrix 1 0.018228 -0.023918 -0.004047 0.014295 0.004610 0.007284 -0.000000 -0.023918 0.122461 -0.007904 -0.037049 -0.016175 -0.009571 -0.000000 -0.004047 -0.007904 0.001619 -0.002112 0.000250 0.001154 -0.000000 0.014295 -0.037049 -0.002112 0.213449 0.005019 -0.001280 -0.000000 0.004610 -0.016175 0.000250 0.005019 0.015620 0.005263 -0.000000 0.007284 -0.009571 0.001154 -0.001280 0.005263 0.009548 -0.000000 -0.000000 -0.000000 -0.000000 -0.000000 -0.000000 -0.000000 -0.000000 Matrix 2 0.021744 0.153683 0.005159 0.064664 0.030826 0.019943 0.000000 Thank You Abhishek Agrawal SUNY- Buffalo (716-435-7122) On Sun 11/08/09 8:47 PM , "Edward J.
