Hi Diana, SparkALS is an example implementation of ALS. It doesn't call the ALS algorithm implemented in MLlib. M, U, and F are used to generate synthetic data.
I'm updating the examples. In the meantime, you can take a look at the updated MLlib guide: http://50.17.120.186:4000/mllib-collaborative-filtering.html and try the example code there.
