> It would be good to support variables in resources and users.
> E.g.
> HDFS Resource =  /home/$user  
> or
> Table Resource = ${user}_*
> Users allowed = $user
> Where $user will be expanded to the current user. 
> I think, resource substitution will be easy. For permission, we can use key 
> word like we use for all users group="public". We can use key word like 
> "USER" or something like that.
