meiyoula created SPARK-8392:
-------------------------------

             Summary: the process is hang on when getting cachedNodes
                 Key: SPARK-8392
                 URL: https://issues.apache.org/jira/browse/SPARK-8392
             Project: Spark
          Issue Type: Bug
          Components: Spark Core
            Reporter: meiyoula


*def getAllNodes: Seq[RDDOperationNode] = {
    _childNodes ++ _childClusters.flatMap(_.childNodes)
  }*
when the _childClusters has so many nodes, the process will hang on. I think we can improve the efficiency here.
