> 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/localhost@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?
