> Currently, it would throw exception if I try to register user function
> multiple times. Registering udf multiple times is very common usage in
> notebook scenario. And I don't think it would cause issues for users.
> e.g. If user happened to register the same udf multiple times (he intend to
> register 2 different udf actually), then he would get exception at runtime
> where he use the udf that is missing registration.
