[jira] [Created] (SPARK-25758) Deprecate BisectingKMeans compute cost

Marco Gaido created SPARK-25758:
-----------------------------------

             Summary: Deprecate BisectingKMeans compute cost
                 Key: SPARK-25758
                 URL: https://issues.apache.org/jira/browse/SPARK-25758
             Project: Spark
          Issue Type: Improvement
          Components: ML
    Affects Versions: 2.4.0
            Reporter: Marco Gaido


In SPARK-23451 the method {{computeCost}} from KMeans was deprecated, as we have now a better way to evaluate a clustering algorithm (the {{ClusteringEvaluator}}). Moreover, in the deprecation, the method was targeted for removal in 3.0.

I think we should deprecate the computeCost method on BisectingKMeans  for the same reasons.
