Hi Xiangrui,
Commenting!
> TrainValidationSplit is missing in pyspark.ml.tuning
> ----------------------------------------------------
>
> 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.
