* Disabled excessive Spark logging in tests * Fixed a singature of XGBoostModel.predict Prior to this commit XGBoostModel.predict produced an RDD with an array of predictions for each partition, effectively changing the shape wrt the input RDD. A more natural contract for prediction API is that given an RDD it returns a new RDD with the same number of elements. This allows the users to easily match inputs with predictions. This commit removes one layer of nesting in XGBoostModel.predict output. Even though the change is clearly non-backward compatible, I still think it is well justified. * Removed boxing in XGBoost.fromDenseToSparseLabeledPoints * Inlined XGBoost.repartitionData An if is more explicit than an opaque method name. * Moved XGBoost.convertBoosterToXGBoostModel to XGBoostModel * Check the input dimension in DMatrix.setBaseMargin Prior to this commit providing an array of incorrect dimensions would have resulted in memory corruption. Maybe backport this to C++? * Reduced nesting in XGBoost.buildDistributedBoosters * Ensured consistent naming of the params map * Cleaned up DataBatch to make it easier to comprehend * Made scalastyle happy * Added baseMargin to XGBoost.train and trainWithRDD * Deprecated XGBoost.train It is ambiguous and work only for RDDs. * Addressed review comments * Revert "Fixed a singature of XGBoostModel.predict" This reverts commit 06bd5dcae7780265dd57e93ed7d4135f4e78f9b4. * Addressed more review comments * Fixed NullPointerException in buildDistributedBoosters
