             Summary: User Defined Type registration without SQLUserDefinedType annotation
                 Key: SPARK-14487
                 URL: https://issues.apache.org/jira/browse/SPARK-14487
             Project: Spark
          Issue Type: Improvement
            Reporter: Liang-Chi Hsieh


Currently we use SQLUserDefinedType annotation to register UDTs for user classes. However, by doing this, we add Spark dependency to user classes.

For some user classes, it is unnecessary to add such dependency that will increase deployment difficulty.

We should provide alternative approach to register UDTs for user classes without SQLUserDefinedType annotation.
