(Bug fixes are good, if you can separate those out, those should not be controversial.)
I am still skeptical of new blobs of code, as these have been a big problem for the project. If it's clean, follows existing code and APIs, and you are willing to actively support it, it may be un-harmful. I am not going to be able to work on Mahout in any significant way any more, so would not feel right committing this myself, especially if the expectation was that I would be able to help modify and support these changes. But, leave it to other committers to take that up. It sounds lik eyou have made a lot of effort to weave it in nicely. > Now it is integrable to Mahout, and can work with Mahout's existing > Recommender interface.
