Subject [jira] [Commented] (HIVE-17129) Increase usage of InterfaceAudience and InterfaceStability annotations
Date Fri, 28 Jul 2017 17:06:00 GMT

    [ https://issues.apache.org/jira/browse/HIVE-17129?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16105311#comment-16105311

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?

> 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.
