Hi Sean: 
            Thanks for the reply.
            Assume I have only one table named 'movie' with 1000+ records, this table have three columns:'id','movieName','movieDescription'.
            Can Mahout calculate the most similar movies for a movie.(based on only the 'movie' table)? 
            code like: List mostSimilarMovieList = recommender.mostSimilar(int movieId).
            if not, do you have any suggestions for this scenario?
