             Summary: 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: 2.3.1, 2.3.0
            Reporter: Simeon H.K. Fitch


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}

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.
