--------------------------------------
After seeing this:
http://stackoverflow.com/questions/9708427/hadoop-matrix-multiplication
I guess we should get a first scratch implementation based on this MPI version:

It's quite easy, the first matrix A must be row-partitioned and the second
matrix must be available in every peer.
