Subject Re: Grouplens dataset Recommenderjob with Hadoop

I am not sure what you are trying to do.

The class you wrote looks fine for the purpose below -- except that in
the constructor you try to run a full evaluation of the recommender!
That's definitely not right. Remove that.

But if you are trying to run an eval, then that has nothing to do with
Hadoop, so the command below doesn't make sense.
