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

             Summary: Decision Tree training: prevNodeIdsForInstances.unpersist() at end of training
                 Key: SPARK-9962
                 URL: https://issues.apache.org/jira/browse/SPARK-9962
             Project: Spark
          Issue Type: Improvement
          Components: ML
            Reporter: Joseph K. Bradley
            Priority: Minor


NodeIdCache: prevNodeIdsForInstances.unpersist() needs to be called at end of training.

This applies to both the ML and MLlib implementations, but it is Ok to skip the MLlib implementation since it will eventually be replaced by the ML one.
