---------------------------------------------------------------

[~josephkb] It is ml.tree.impl.GradientBoostedTrees not 
spark.mllib.GradientBoostedTrees that provide this method. 
Do you mean that a evaluateEachIteration method is added and called in GBTs' 
fit method?
I am willing to work on this.
