             Summary: Hive authorization should use short username when Kerberos authentication
                 Key: HIVE-3807
                 URL: https://issues.apache.org/jira/browse/HIVE-3807
             Project: Hive
          Issue Type: Improvement
          Components: Authorization
    Affects Versions: 0.9.0
            Reporter: Kai Zheng


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.
