-------------------------------------

             Summary: k-means save/load should put one cluster per row
                 Key: SPARK-14646
                 URL: https://issues.apache.org/jira/browse/SPARK-14646
             Project: Spark
          Issue Type: Improvement
          Components: ML
    Affects Versions: 1.6.1
            Reporter: Xiangrui Meng
            Assignee: Xiangrui Meng
            Priority: Minor


We store k-means clusters in a single row in the current implementation. It would be better to store the clusters one per row. So it is easier to add more columns like size, cost, etc. We may consider backward compatibility.
