> Currently when authentication method is Kerberos,Hive authorization uses user full name as privilege principal, for example, it uses john@EXAMPLE.COM instead of john.
> It should use the short name instead. The benefits:
> 1. Be consistent. Hadoop, HBase and etc they all use short name in related ACLs or authorizations. For Hive authorization works well with them, this should be.
> 2. Be convenient. It's very inconvenient to use the lengthy Kerberos principal name when grant or revoke privileges via Hive CLI.
