             Summary: Check model save/load for MLlib 1.4
                 Key: SPARK-7541
                 URL: https://issues.apache.org/jira/browse/SPARK-7541
             Project: Spark
          Issue Type: Sub-task
          Components: ML, MLlib, PySpark
            Reporter: Joseph K. Bradley


For each model which supports save/load methods, we need to verify:
* These methods are tested in unit tests in Scala and Python (if save/load is 
supported in Python).
* If a model's name, data members, or constructors have changed _at all_, then 
we likely need to support a new save/load format version.  Different versions 
must be tested in unit tests to ensure backwards compatibility (i.e., verify we 
can load old model formats).
