> Currently, in spark.mllib, generalized linear regression models like
> LinearRegressionModel, RidgeRegressionModel and LassoModel support predict()
> via: LinearRegressionModelBase.predict, which only takes single rows (feature
> vectors).
> It should support batch prediction, taking an RDD. (See other classes which
> do this already such as NaiveBayesModel.)
