[jira] [Created] (SPARK-12379) Copy GBT implementation to spark.ml

Seth Hendrickson created SPARK-12379:
----------------------------------------

             Summary: 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.
