Yuhao Yang 8cffcb60de [SPARK-14322][MLLIB] Use treeAggregate instead of reduce in OnlineLDAOptimizer ... ## What changes were proposed in this pull request? jira: https://issues.apache.org/jira/browse/SPARK-14322 OnlineLDAOptimizer uses RDD.reduce in two places where it could use treeAggregate. This can cause scalability issues. This should be an easy fix. This is also a bug since it modifies the first argument to reduce, so we should use aggregate or treeAggregate. See this line: f12f11e578/mllib/src/main/scala/org/apache/spark/mllib/clustering/LDAOptimizer.scala (L452) and a few lines below it. ## How was this patch tested? unit tests Author: Yuhao Yang <hhbyyh@gmail.com> Closes #12106 from hhbyyh/ldaTreeReduce.		2016-04-06 11:36:26 -07:00
