----------------------------------
Hi, [~tedyu], [~anoop.hbase]
I do not find an option in the menu for me to add release note. Probably I do
not have the permission.
Here is the info that needs to be added. Feel free to change the wording as
you desire. Thanks.
-------------------------------------------------
The system visibility label authorization for super users will no longer be
persisted in hbase:labels table. Super users will be determined at server
startup time. They will have all the permissions for Visibility labels.
If you have a prior deployment that had super users' system label persisted in
hbase:labels, you can clean up by invoking the shell command 'clear_auths'.
For example: clear_auths 'old_superuser', 'system'
This is particular necessary when you change super users, i.e. a previous super
user is no longer a super user.

> Project: HBase
> Issue Type: Bug
> Components: security
> Affects Versions: 0.98.8, 0.99.2
> Reporter: Jerry He
> Assignee: Jerry He

>
> Super users have all the permissions for ACL and Visibility labels.
> They are defined in hbase-site.xml.
> Currently in VisibilityController, we persist super user with their system
> permission in hbase:labels.
> This makes change in super user difficult.
> There are two issues:
> In the current DefaultVisibilityLabelServiceImpl.addSystemLabel, we only add
> super user when we initially create the 'system' label.
> No additional update after that even if super user changed. See code for
> details.
>
> Additionally, there is no mechanism to remove any super user from the labels
> table.
>
> We probably should not persist super users in the labels table.
> They are in hbase-site.xml and can just stay in labelsCache and used from
> labelsCache after retrieval by Visibility Controller.
