Wojciech Jurczyk created SPARK-12877:
----------------------------------------
Summary: TrainValidationSplit is missing in pyspark.ml.tuning
Key: SPARK-12877
URL: https://issues.apache.org/jira/browse/SPARK-12877
Project: Spark
Issue Type: Bug
Components: PySpark
Affects Versions: 1.6.0
Reporter: Wojciech Jurczyk
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.
