You can do grid search if you set the evaluator to a
MulticlassClassificationEvaluator, which expects a prediction column, not a
rawPrediction column. There's a JIRA for making
BinaryClassificationEvaluator accept prediction instead of rawPrediction.

Someone correct me if I'm wrong but no there isn't one that I am aware of.
Unless someone is willing to explain how to obtain the raw prediction
column with the GBTClassifier. In this case I'd be happy to work on a PR.

Hi Benjamin,
Thanks, the documentation you sent is clear.
Is there any other way to perform a Grid Search with GBT?

Hi Ndjido,
This is because GBTClassifier doesn't yet have a rawPredictionCol like the.
RandomForestClassifier has.

Hi Joseph,
Yes Random Forest support Grid Search on Spark 1.5.+ . But I'm getting a
"rawPredictionCol field does not exist exception" on Spark 1.5.2 for
Gradient Boosting Trees classifier.

It should work with 1.5+.

Hi folks,
Does anyone know whether the Grid Search capability is enabled since the issue
spark-9011 of version 1.4.0 ? I'm getting the "rawPredictionCol column doesn't
exist" when trying to perform a grid search with Spark 1.4.0.
Cheers,
Ardo
