> 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.
