---------------------------------------
I am working on a solution.
> "evaluateEachIteration" will fail on trying to run it on a model with 500+
> trees
> ---------------------------------------------------------------------------------
>
> Key: SPARK-15858
> URL: https://issues.apache.org/jira/browse/SPARK-15858
> Project: Spark
> 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
