Thomas Jungblut commented on HAMA-221:
--------------------------------------
Okay if you really want to benchmark it:
https://github.com/thomasjungblut/thomasjungblut-common/blob/master/src/de/jungblut/math/bsp/MatrixMultiplicationBSP.java
I have just extracted my math lib to
https://github.com/thomasjungblut/tjungblut-math
You can build it like usually with maven.
What you need though is the VectorWritable class:
https://github.com/thomasjungblut/thomasjungblut-common/blob/master/src/de/jungblut/clustering/model/VectorWritable.java
This should be fine usable with Hama-0.4, Hadoop 20.2 and Java6.
