[jira] [Created] (SPARK-3261) KMeans clusterer can return duplicate cluster centers

Derrick Burns created SPARK-3261:
------------------------------------

             Summary: KMeans clusterer can return duplicate cluster centers
                 Key: SPARK-3261
                 URL: https://issues.apache.org/jira/browse/SPARK-3261
             Project: Spark
          Issue Type: Bug
          Components: MLlib
    Affects Versions: 1.0.2
            Reporter: Derrick Burns


This is a bad design choice.  I think that it is preferable to produce no duplicate cluster centers. So instead of forcing the number of clusters to be K, return at most K clusters.
