> Bellow is the code of using the string of current user object as the "user" 
> value.
> {code}
>     entity.addPrimaryFilter("user", UserGroupInformation.getCurrentUser()
>         .toString());
> {code}
> When we use kerberos authentication, it's going to output the full name, such 
> as "zjshen/localhost@LOCALHOST (auth.KERBEROS)". It is not user friendly for 
> searching by the primary filters. It's better to use shortUserName instead.
