------------------------------------
Assignee: Apache Spark
> Use treeReduce instead of reduce in OnlineLDAOptimizer

> Project: Spark
> Issue Type: Improvement
> Components: ML, MLlib
> Reporter: Joseph K. Bradley
> Assignee: Apache Spark
>
> OnlineLDAOptimizer uses {{RDD.reduce}} in two places where it could use
> treeReduce. This can cause scalability issues. This should be an easy fix.
> See this line:
