Thejas M Nair updated HIVE-5928:
--------------------------------
Description:
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.

This jira proposes a new interface HiveBaseAuthorizationProvider that does not
make assumptions of the privileges required for the actions. The authorize()
functions will be equivalent of authorize(<hive object>, <action>). 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. There will be a subclass of
HiveBaseAuthorizationProvider that executes actions using this interface.
