> Using an updated instance of ScalarUserDefinedFunction causes protobuf cast failures on server
> ----------------------------------------------------------------------------------------------
>
> Key: SPARK-44388
> URL: https://issues.apache.org/jira/browse/SPARK-44388
> Project: Spark
> Issue Type: Bug
> Components: Connect
> Affects Versions: 3.5.0
> Reporter: Venkata Sai Akhil Gudesa
> Priority: Major
>
> When running the following code-
> {code:java}
> class A(x: Int) { def get = x * 7 }
> val myUdf = udf((x: Int) => new A(x).get)
> val modifiedUdf = myUdf.withName("myUdf")
> spark.range(5).select(modifiedUdf(col("id"))).as[Int].collect(){code}
> which modifies the original myUdf instance through the `withName` method causes the following error to occur during execution:
> {noformat}
> java.lang.ClassCastException: org.apache.spark.connect.proto.ScalarScalaUDF cannot be cast to com.google.protobuf.MessageLite
