Summary: Add an SQL node as a feature transformer (was: Add an SQL node as
a feature tranformer)
> Add an SQL node as a feature transformer
> ----------------------------------------
>
> Key: SPARK-8345
> URL: https://issues.apache.org/jira/browse/SPARK-8345
> Project: Spark
> Issue Type: New Feature
> Components: ML
> Reporter: Xiangrui Meng
>
> Some simple feature transformations can take leverage on SQL operators. Users
> do not need to create an ML transformer for each of them. We can have an SQL
> transformer that executes an SQL command which operates on the input
> dataframe.
> {code}
> val sql = new SQL()
> .setStatement("SELECT *, length(text) AS text_length FROM __THIS__")
> {code}
> where "__THIS__" will be replaced by a temp table that represents the
> DataFrame.
