>             Project: Spark
>          Issue Type: Improvement
>          Components: SQL
>    Affects Versions: 1.4.1
>            Reporter: Alex Liu

> Since many data sources have UDF and Spark SQL has UDF as well, but it only filters data at Spark SQL side.
> We should create a way to allow push down Spark SQL UDF to datasource UDF.
