1) Have Created pull request.
Basically Moved
1) featureSubsetStrategy to TreeEnsembleParams instead of having it on
RandomForestParams . So that it can be used for both Random Forest and GBT
2 ) Changed DecisionTreeRegressor private train method to pass
featureSubsetStrategy
3) To Test changed GradientBoostedTreeClassifierExample with
val gbt = new GBTClassifier()
.setLabelCol("indexedLabel")
.setFeaturesCol("indexedFeatures")
.setMaxIter(10)
.setFeatureSubsetStrategy("auto")

> Sample from H2O.ai
> gbmParams._col_sample_rate
> Please provide the parameter .
