Hi All, any update on this issue?
> Add fit with validation set to spark.ml GBT
> -------------------------------------------
>
> Key: SPARK-7132
> URL: https://issues.apache.org/jira/browse/SPARK-7132
> Project: Spark
> Issue Type: Improvement
> Components: ML
> Reporter: Joseph K. Bradley
> Priority: Minor
>
> In spark.mllib GradientBoostedTrees, we have a method runWithValidation which takes a validation set. We should add that to the spark.ml API.
> This will require a bit of thinking about how the Pipelines API should handle a validation set (since Transformers and Estimators only take 1 input DataFrame). The current plan is to include an extra column in the input DataFrame which indicates whether the row is for training, validation, etc.
