Manoj Kumar updated SPARK-6158:
-------------------------------
Description:
1. a] When an instance of GradientBoostedTrees class is called and run, the
boost method in the GradientBoostedTrees object is called ultimately. b] When a
GradientBoostedTrees object is created and train is called, an instance of
GradientBoostedTrees is created internally and this calls the boost method in a
newly instantiated GradientBoostedTrees object which is confusing!
2. I require the finally trained models in the private method boost, for this
(https://issues.apache.org/jira/browse/SPARK-6025) (to prevent repeated
training). Thus it makes sense to move boost to the class GradientBoostedTrees
where runWithValidation is already present.
