[jira] [Created] (SPARK-9918) Remove runs from KMeans under the pipeline API

Xiangrui Meng created SPARK-9918:
------------------------------------

             Summary: Remove runs from KMeans under the pipeline API
                 Key: SPARK-9918
                 URL: https://issues.apache.org/jira/browse/SPARK-9918
             Project: Spark
          Issue Type: Improvement
          Components: MLlib
    Affects Versions: 1.5.0
            Reporter: Xiangrui Meng
            Assignee: Xiangrui Meng


This requires some discussion. I'm not sure whether `runs` is a useful parameter. It certainly complicates the implementation. We might want to optimize the k-means implementation with block matrix operations. In this case, having `runs` may not be worth the trade-offs.
