Simeon H.K. Fitch updated SPARK-24649:
--------------------------------------
Description:
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}
was:

Scala automatically generates an `unapply` method for the primary constructor
of case classes in the companion object. An appropriate fix for this would to
manually provide a secondary `unapply` method for the 2.2.x signature.
