>
> Key: SPARK-12877
> URL: https://issues.apache.org/jira/browse/SPARK-12877
> Project: Spark
> Issue Type: New Feature
> Components: PySpark
> Affects Versions: 1.6.0
> Reporter: Wojciech Jurczyk
> Fix For: 2.0.0
>
>
> I was investingating progress in SPARK-10759 and I noticed that there is no TrainValidationSplit class in pyspark.ml.tuning module.
> Java/Scala's examples SPARK-10759 use org.apache.spark.ml.tuning.TrainValidationSplit that is not available from Python and this blocks SPARK-10759.
> Does the class have different name in PySpark, maybe? Also, I couldn't find any JIRA task to saying it need to be implemented. Is it by design that the TrainValidationSplit estimator is not ported to PySpark? If not, that is if the estimator needs porting then I would like to contribute.
