> The existing HiveAuthorizationProvider interface implementations can be used
> to support custom authorization models.
> But this interface limits the customization for these reasons -
> 1. It has assumptions about the privileges required for an action.
> 2. It does have not functions that you can implement for having custom ways
> of doing the actions of access control statements.
> This jira proposes a new interface HiveAuthorizer that does not make
> assumptions of the privileges required for the actions. The authorize()
> functions will be equivalent of authorize(<operation type>, <input objects>,
> <output objects>). It will also have functions that will be called from the
> access control statements.
> The current HiveAuthorizationProvider will continue to be supported for
> backward compatibility.
