Ashutosh Chauhan updated HIVE-3807:
-----------------------------------

        Fix Version/s:     (was: 0.9.0)
    Affects Version/s: 0.10.0
               Status: Open  (was: Patch Available)

Tests did pass. However this looks like an incompatible change. Isn't it? These 
names are stored in metastore. After the change shortName will be compared 
against long name for users for whom privileges have already been granted. Than 
check will fail and privileged user will not be allowed to do actions. 
Workaround will be to grant privileges to such users again with short names. 
Kai, can you run some tests to verify if the problem which I identified does 
exist and workaround will actually work.

> Currently when authentication method is Kerberos,Hive authorization uses user 
> full name as privilege principal, for example, it uses j...@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.
