------------------------------------
Summary: Add Bucketizer
Key: SPARK-5893
URL: https://issues.apache.org/jira/browse/SPARK-5893
Project: Spark
Issue Type: Sub-task
Components: ML
Reporter: Xiangrui Meng
`Bucketizer` maps a column of continuous features to a column of feature
buckets, where the buckets are specified by users.
{code}
val bucketizer = new Bucketizer()
.setInputCol("age")
.setBuckets(Array(10, 20, 30, 40, 50))
.setOutputCol("ageBuckets")
{code}
The output feature names should be automatically generated. We need to discuss
the behavior if a value falls out the specified bucket range.
