                 Key: SPARK-15858
                 URL: https://issues.apache.org/jira/browse/SPARK-15858

          Issue Type: Bug
    Affects Versions: 1.6.1, 2.0.0
            Reporter: Mahmoud Rawas


this line:
remappedData.zip(predictionAndError).mapPartitions 
causing a stack over flow exception on executors after nearly 300 iterations also with this number of trees having a var RDD will have needless memory allocation. 
this functionality tested on version 1.6.1
