Joseph K. Bradley commented on SPARK-3703:
------------------------------------------

Currently, none of these generic ensembles are targeted for 1.5.  I definitely 
want to add them at some point, but I hesitate to suggest working on them since 
we have such limited time for reviewing.  Improvements to existing ensembles 
are higher priority right now.  For that, I'd suggest one of these:
* [SPARK-6684]
* [SPARK-7674], adding stats for ensembles following the example set for linear 
regression

> This is a general JIRA for coordinating on adding ensemble learning methods 
> to MLlib.  These methods include a variety of boosting and bagging 
> algorithms.  Below is a general design doc for ensemble methods (currently 
> focused on boosting).  Please comment here about general discussion and 
> coordination; for comments about specific algorithms, please comment on their 
> respective JIRAs.
