Hi Sean Owen, Thanks for quick response and sorry for late response (I am a bit surprised that I didn't received your response in my mail box, not even in spam folder). I saw your response at http://comments.gmane.org/gmane.comp.apache.mahout.user/10901
I don't understand your meaning of "It will perform perfectly as a result; you're not actually testing it." Is that means I need to implement MySQLDataModelBuilder which will return GenericDataModel? Please advice.
