pralabhkumar commented on SPARK-20199:
--------------------------------------
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")
> GradientBoostedTreesModel doesn't have featureSubsetStrategy parameter
