Joseph K. Bradley commented on SPARK-7130:
------------------------------------------
Actually, now that I'm thinking about this, I'm wondering if it matters. I
believe I wrote the JIRA thinking it would be cleaner, but I don't think it
really matters unless someone can present a real case for it. (Let me know if
you have a use case where it matters.)
Thanks for pinging on the JIRA first, before working on it!
> spark.ml RandomForest* should always do bootstrapping
> -----------------------------------------------------
>
> Key: SPARK-7130
> URL: https://issues.apache.org/jira/browse/SPARK-7130
> Project: Spark
> Issue Type: Improvement
> Components: ML
> Affects Versions: 1.4.0
> Reporter: Joseph K. Bradley
> Priority: Minor
>
> Currently, spark.ml RandomForest does not do bootstrapping if numTrees = 1.
> For consistency and a simpler API, it should always do bootstrapping. The
> current behavior is an artifact of the old API, in which RandomForest and
> DecisionTree share the same implementation. This change should happen after
> the implementation is moved to spark.ml (which we need to do so that the
> implementation can be generalized).
