------------------------------------

             Summary: StreamingLinearRegression should return a DStream of 
weights when calling trainOn
                 Key: SPARK-4722
                 URL: https://issues.apache.org/jira/browse/SPARK-4722
             Project: Spark
          Issue Type: Improvement
          Components: MLlib, Streaming
            Reporter: Arthur Andres
            Priority: Minor


When training a model with a stream of new data (Spark Streaming + Spark 
Mlllib),  the weights (and the other part of the regression model) update at 
every iterations.
At the moment the only output we can get is the prediction when calling 
predictOn (class StreamingLinearRegression)
It would be a nice improvement if trainOn would return a Dstream of weights 
(and any other underlying model data) so we can access it and see it evolve. At 
the moment they are only outputted in the log
For example this could then be saved so when reloading the application we can 
access this information without having to train the model again.
