     [ https://issues.apache.org/jira/browse/SPARK-25758?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Sean Owen updated SPARK-25758:
------------------------------
    Priority: Minor  (was: Major)

(Not major). I agree with deprecating it. It does not need to block 2.4.

> 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.
