You should have a look at the Mahout in Action book.

Nonetheless, this
the book shows the basics of making a recommender. In the example they
are using GenericUserBasedRecommender, in your case you would need a
SVDRecommender and you tell that recommender the type of Factorizer you
want to use, e.g. ALSWRFactorizer. That said, for a SVDRecommender you
don't need to specify a sense of similarity nor of neighborhood. However,
you can specify sampling strategies and/or whether the generated model
should be persisted (to avoid recalculating if you don't need to. Hope that
