Subject kMeans Implementation
Date Tue, 04 Mar 2014 10:43:08 GMT
I was studying Mahout libraries and I found something of strange in your 
kMeans implementation.

I was looking inside it and I have noticed that kMeans only uses map 
functions, omitting the reducers. Why have you done this choice?
It is not using MapReduce programming model even if it is declared that 
the Mahout's core is Hadoop.
Is this choice driven by performance issue?

Best regards
