[jira] [Created] (SPARK-7647) Additional methods in JavaModel wrappers

Xiangrui Meng created SPARK-7647:
------------------------------------

             Summary: Additional methods in JavaModel wrappers
                 Key: SPARK-7647
                 URL: https://issues.apache.org/jira/browse/SPARK-7647
             Project: Spark
          Issue Type: New Feature
          Components: ML, PySpark
    Affects Versions: 1.4.0
            Reporter: Xiangrui Meng


We wrap Scala implementation of estimators and models as JavaEstimator and JavaModel in Python, which provides fit/transform by default. However, no additional methods are provided under the Python API. So basically user can call transform but they cannot get model weights out. We should provide those methods.
