About kmeans mapreduce implementation

Hi,
I'm trying to understand Mahout kmeans mapreduce implementation.
I've gone through the mapreduce tutorial at http://hadoop.apache.org/docs/stable/mapred_tutorial.html
which I kind of understood.

However, I could not understand the logic of kmeans implementation in Mahout 0.8. For example there seems to be no Mapper and Reducer implementations for kmeans (In previous versions of Mahout there are KmeansMapper and KmeansReducer though)

Any help or pointers to tutorials will be appriciated.

Thanks
Ahmet

I guess you are looking for ClusterClassificationDriver and its related
Mapper.
