[jira] [Created] (SPARK-9122) spark.mllib regression should support batch predict

Joseph K. Bradley created SPARK-9122:

             Summary: spark.mllib regression should support batch predict
                 Key: SPARK-9122
                 URL: https://issues.apache.org/jira/browse/SPARK-9122
             Project: Spark
          Issue Type: Improvement
          Components: MLlib, PySpark
            Reporter: Joseph K. Bradley


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.)
