------------------------------------

             Summary: OnlineSummarizer doesn't merge mean correctly
                 Key: SPARK-4355
                 URL: https://issues.apache.org/jira/browse/SPARK-4355
             Project: Spark
          Issue Type: Bug

    Affects Versions: 1.0.2, 1.1.1, 1.2.0

It happens when the mean on one side is zero. I will send an PR with some code clean-up.
