Sergio Peña commented on HIVE-17129:
------------------------------------
{{MetaStoreEventListener}} is used by other components, so this must be public.
Regarding {{ListenerEvent}}, I don't know. It is not used directly, but is used
by inherited objects that {{MetaStoreEventListener}} uses, such as
{{CreateTableEvent}}.
How does this work? If you mark {{ListenerEvent}} as private, then can users
use {{CreateTableEvent}} for instance?
> Increase usage of InterfaceAudience and InterfaceStability annotations

> The {{InterfaceAudience}} and {{InterfaceStability}} annotations were added a
> while ago to mark certain classes as available for public use. However, they
> were only added to a few classes. The annotations are largely missing for
> major APIs such as the SerDe and UDF APIs. We should update these interfaces
> to use these annotations.
> When done in conjunction with HIVE-17130, we should have an automated way to
> prevent backwards incompatible changes to Hive APIs.
