             Summary: Resolve code duplication for classification/regression summarizers
                 Key: SPARK-21245
                 URL: https://issues.apache.org/jira/browse/SPARK-21245
             Project: Spark
          Issue Type: Sub-task
          Components: ML
    Affects Versions: 2.2.1
            Reporter: Seth Hendrickson


In several places (LogReg, LinReg, SVC) in Spark ML, we collect summary information about training data using {{MultivariateOnlineSummarizer}} and {{MulticlassSummarizer}}. We have the same code appearing in several places (and including test suites). We can eliminate this by creating a common implementation somewhere.
