>    Affects Versions: 2.0.0

> Whne using MiniKDC and the minicluster in a unit test, there is a conflict 
> causeed by HBaseTestingUtility:
> {code}
>   public static User getDifferentUser(final Configuration c,
>     final String differentiatingSuffix)
>   throws IOException {
>    // snip
>     String username = User.getCurrent().getName() +
>       differentiatingSuffix; <==================== problem here
>     User user = User.createUserForTesting(c, username,
>         new String[]{"supergroup"});
>     return user;
>   }
> {code}
> This creates users like securedUser/localh...@example.com.hfs.0, and this 
> does not work.
> My fix is to return the current user when Kerberos is set. I don't think that 
> there is another option (any other opinion?). However this user is not in a 
> group so we have logs like 'WARN  [IPC Server handler 9 on 61366] 
> security.UserGroupInformation (UserGroupInformation.java:getGroupNames(1521)) 
> - No groups available for user securedUser' I'm not sure of its impact. 
> [~apurtell], what do you think?
