> 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
> Priority: Minor
> Labels: starter
>
> 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.
