Major Description
The last few releases, we changed the interface of ScalaUDF. Unfortunately, some Spark Package (spark-deep-learning) are using our internal class `ScalaUDF`. In the release 2.3, we added new parameters into these class. The users hit the binary compatibility issues and got the exception:
> java.lang.NoSuchMethodError: org.apache.spark.sql.catalyst.expressions.ScalaUDF.<init>(Ljava/lang/Object;Lorg/apache/spark/sql/types/DataType;Lscala/collection/Seq;Lscala/collection/Seq;Lscala/Option;)V
