Hi Aris,
Thanks for the interest. First and foremost, tree ensembles are a top priority for the 1.2 release and we are working hard towards it. A random forests PR is already under review and AdaBoost and gradient boosting will be added soon after. Unfortunately, the GBDT branch I shared is way off master. There has been a lot of under-the-hood optimizations for decision trees and I am not surprised that the branch doesn't compile. It will be best if you could wait for a few days till I make the branch compatible with the latest master. Again, thanks for your interest in boosting algos. We are eager to add them to MLlib ASAP.
