Matrix Multiplication of two RDD[Array[Double]]'s

[Liquan Pei]

Hi

I am currently implementing an algorithm involving matrix multiplication.
Basically, I have matrices represented as RDD[Array[Double]]. For example,
If I have A:RDD[Array[Double]] and B:RDD[Array[Double]] and what would be
the most efficient way to get C = A * B

Both A and B are large, so it would not be possible to save either of them
in memory.

Thanks a lot for your help!
