-----------------------------------------
Summary: Avoid creating duplicate ids in OnlineLDAOptimizer
Key: SPARK-14370
URL: https://issues.apache.org/jira/browse/SPARK-14370
Project: Spark
Issue Type: Improvement
Components: MLlib
Reporter: Joseph K. Bradley
Priority: Trivial
In {{OnlineLDAOptimizer}}'s {{submitMiniBatch}} method, we create a list of ids
{{val ids: List[Int]}} before calling {{variationalTopicInference}}, which then
creates a duplicate set of ids. {{variationalTopicInference}} should reuse the
same set.
