Anoop Sam John commented on HBASE-11434:
----------------------------------------
{code}
+ // set up the list of users with superuser privilege
+ superusers = Lists.asList(userProvider.getCurrentUserName(),
+ conf.getStrings(AccessControlLists.SUPERUSER_CONF_KEY, new String[0]));
{code}
And UserProvider#getCurrentUserName() returns user.getName().
We should use user.getShortName() (?)
And previously this List of users were creating by
{code}
- String currentUser = user.getShortName();
- List<String> superusers = Lists.asList(currentUser, conf.getStrings(
- AccessControlLists.SUPERUSER_CONF_KEY, new String[0]));
{code}
So we used getShortName().

> The AccessController allows users to store cells with ACL tags encoded by the
> client. This isn't a security issue currently, because in order to store the
> cell the user must have a relevant WRITE grant, and the user is allowed to
> specify whatever ACL for the cell they'd like. However it could become a
> correctness problem in the future, if we introduce format sanity checking or
> the like, so let's disallow inbound mutations containing cells with reserved
> tags like the VisibilityController does.
> The check is skipped if the active user is a superuser. First, superusers are
> allowed to do anything. Second, replication (as superuser) must be able to
> store incoming cells with ACL tags.
