Hyukjin Kwon resolved SPARK-24649.
----------------------------------
Resolution: Invalid
catalysis is considered as an internal API, and subject to change between minor
releases.
> SparkUDF.unapply is not backwards compatable
> --------------------------------------------
>
> Key: SPARK-24649
> URL: https://issues.apache.org/jira/browse/SPARK-24649
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Affects Versions: 2.3.0, 2.3.1
> Reporter: Simeon H.K. Fitch
> Priority: Minor
>
> The shape of the `ScalaUDF` case class changed in 2.3.0. A secondary
> constructor that's backwards compatible with 2.1.x and 2.2.x was provided,
> but a corresponding `unapply` method wasn't included. Therefore code such as
> the following that worked in 2.1.x and 2.2.x no longer compiles:
> {code:java}
> val ScalaUDF(function, dataType, children, inputTypes, udfName) = myUDF
> {code}
