Nick Pentreath commented on SPARK-7290:
---------------------------------------
Is this still desired? Seems it perhaps doesn't add that much over existing
functionality. We should perhaps rather focus on things like adding multi-col
support for {{StringIndexer}} and {{OneHotEncoder}} to enhance efficiency.

> `StringVectorizer` maps a String column into a vector column with binary
> values. The output should be the same as chaining `StringIndexer` and
> `OneHotEncoder`.
