---------------------------------------
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.
