Apache Spark reassigned SPARK-12379:
------------------------------------
Assignee: (was: Apache Spark)
> Copy GBT implementation to spark.ml
> -----------------------------------
>
> Key: SPARK-12379
> URL: https://issues.apache.org/jira/browse/SPARK-12379
> Project: Spark
> Issue Type: Sub-task
> Components: ML, MLlib
> Reporter: Seth Hendrickson
>
> Currently, GBTs in spark.ml wrap the implementation in spark.mllib. This is
> preventing several improvements to GBTs in spark.ml, so we need to move the
> implementation to ml and use spark.ml decision trees in the implementation.
> At first, we should make minimal changes to the implementation.
> Performance testing should be done to ensure there were no regressions.
