Joseph K. Bradley created SPARK-3751:
----------------------------------------

             Summary: DecisionTreeRunner functionality improvement
                 Key: SPARK-3751
                 URL: https://issues.apache.org/jira/browse/SPARK-3751
             Project: Spark
          Issue Type: Improvement
          Components: MLlib
            Reporter: Joseph K. Bradley
            Priority: Minor


DecisionTreeRunner functionality additions:
* Allow user to pass in a test dataset
* Do not print full model if the model is too large.

As part of this, modify DecisionTreeModel and RandomForestModel to allow printing less info.  Proposed updates:
* toString: prints model summary
* toDebugString: prints full model (named after RDD.toDebugString)
