Xiangrui Meng updated SPARK-24719:
----------------------------------
Description:
ClusterEvaluator should support integer labels because we output integer labels
in BisectingKMeans.
[https://github.com/apache/spark/blob/master/mllib/src/main/scala/org/apache/spark/ml/clustering/BisectingKMeans.scala#L77].
We should cast numeric types to double in ClusteringEvaluator.
[~mgaido] Do you have time to work on the fix?
