[jira] [Created] (SPARK-14926) OneVsRest labelMetadata uses incorrect name

Joseph K. Bradley created SPARK-14926:
-----------------------------------------

             Summary: OneVsRest labelMetadata uses incorrect name
                 Key: SPARK-14926
                 URL: https://issues.apache.org/jira/browse/SPARK-14926
             Project: Spark
          Issue Type: Bug
          Components: ML
    Affects Versions: 1.6.1, 1.5.2, 1.4.1, 2.0.0
            Reporter: Joseph K. Bradley
            Priority: Trivial


OneVsRestModel applies {{labelMetadata}} to the output column, but the metadata could contain the wrong name.  The attribute name should be modified to match {{predictionCol}}.

Here is the relevant location: [[https://github.com/apache/spark/blob/2a3d39f48b1a7bb462e17e80e243bbc0a94d802e/mllib/src/main/scala/org/apache/spark/ml/classification/OneVsRest.scala#L200]]
