[SPARK-5893]
@jkbradely, JIRA issue
[here](https://issues.apache.org/jira/browse/SPARK-5893).
One thing to make clear, the `buckets` parameter, which is an array of
`Double`, performs as split points. Say,
```scala
buckets = Array(-0.5, 0.0, 0.5)
```
splits the real number into 4 ranges, (-inf, -0.5], (-0.5, 0.0], (0.0,
0.5], (0.5, +inf), which is encoded as 0, 1, 2, 3.
