Huaxin Gao created SPARK-30630:
----------------------------------

             Summary: Deprecate numTrees in GBT
                 Key: SPARK-30630
                 URL: https://issues.apache.org/jira/browse/SPARK-30630
             Project: Spark
          Issue Type: Improvement
          Components: ML
    Affects Versions: 2.4.5, 3.0.0
            Reporter: Huaxin Gao


Currently, GBT has
{code:java}
/**
 * Number of trees in ensemble
 */
@Since("2.0.0")
val getNumTrees: Int = trees.length{code}
and
{code:java}
/** Number of trees in ensemble */
val numTrees: Int = trees.length{code}
I will deprecate numTrees in 2.4.5 and remove it in 3.0.0
