Joseph K. Bradley commented on SPARK-7127:
------------------------------------------
I don't think a small patch like this requires a design doc. If you have
questions about design, feel free to ask here. You can also do a WIP pull
request, if there are implementation details which are hard to figure out.
> Broadcast spark.ml tree ensemble models for predict
> ---------------------------------------------------
>
> Key: SPARK-7127
> URL: https://issues.apache.org/jira/browse/SPARK-7127
> Project: Spark
> Issue Type: Improvement
> Components: ML
> Affects Versions: 1.4.0
> Reporter: Joseph K. Bradley
> Priority: Minor
> Labels: starter
>
> GBTRegressor/Classifier and RandomForestRegressor/Classifier should broadcast
> models and then predict. This will mean overriding transform().
> Note: Try to reduce duplicated code via the TreeEnsembleModel abstraction.
