Patrick Grandjean updated SPARK-27625:
--------------------------------------
Description:
ScalaRelfection.serializerFor fails for annotated type. Example:
{code:java}
case class Foo(
field1: String,
field2: Option[String] @Bar
)
val rdd: RDD[Foo] = ...
val ds = rdd.toDS // fails at runtime{code}
The stack trace:
{code:java}
// code placeholder
User class threw exception: scala.MatchError: scala.Option[String] @Bar (of
class scala.reflect.internal.Types$AnnotatedType)
