             Summary: Add regParam and featureScaling options to Logistic 
regression 'train' methods
                 Key: SPARK-7134
                 URL: https://issues.apache.org/jira/browse/SPARK-7134
             Project: Spark
          Issue Type: Improvement
          Components: MLlib
            Reporter: Rakesh Chalasani
            Priority: Minor


LogisticRegressionWithSGD is private to mllib and is accessible using "train" 
factory methods. But these train methods do not have provision to set 
regularization parameter or feature scaling. On the other hand, 
LogisticRegressionWithLBFGS is public, the user can set these parameters.

Add a more general train method that allow setting there parameters on the 
model before training.
