> 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.
