[jira] [Created] (SPARK-14386) spark.ml DecisionTreeModel abstraction should not be exposed

Joseph K. Bradley created SPARK-14386:
-----------------------------------------

             Summary: spark.ml DecisionTreeModel abstraction should not be exposed
                 Key: SPARK-14386
                 URL: https://issues.apache.org/jira/browse/SPARK-14386
             Project: Spark
          Issue Type: Improvement
          Components: ML
            Reporter: Joseph K. Bradley
            Assignee: Joseph K. Bradley


In spark.ml, GBT and RandomForest expose the trait DecisionTreeModel in the {{trees}} method, but they should not since it is a private trait (and not ready to be made public).  It will also be more useful to users if we return the concrete types.

Proposal: return concrete types
* The MIMA checks appear to be OK with this change.
