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

             Summary: Forget Unpersist in RandomForest.scala(train Method)
                 Key: SPARK-3918
                 URL: https://issues.apache.org/jira/browse/SPARK-3918
             Project: Spark
          Issue Type: Bug
          Components: MLlib
    Affects Versions: 1.2.0
         Environment: All
            Reporter: junlong
             Fix For: 1.1.0


   In version 1.1.0 DecisionTree.scala, train Method, treeInput has been persisted in Memory, but without unpersist. It caused heavy DISK usage.
   In github version(1.2.0 maybe), RandomForest.scala, train Method, baggedInput has been persisted but without unpersisted too.
