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

             Summary: Bucketizer should include the right most boundary in the last bucket.
                 Key: SPARK-7559
                 URL: https://issues.apache.org/jira/browse/SPARK-7559
             Project: Spark
          Issue Type: Improvement
          Components: ML
    Affects Versions: 1.4.0
            Reporter: Xiangrui Meng
            Assignee: Xiangrui Meng
            Priority: Minor


Now we use special treatment for +inf.  This could be simplified by including the largest split value in the last bucket. E.g., (x1, x2, x3) defines buckets [x1, x2) and [x2, x3]. This shouldn't affect user code much, and there are applications that need to include the right-most value. For example, we can bucketize ratings from 0 to 10 to bad, neutral, and good with splits 0, 4, 6, 10.
