------------------------------------
Summary: Hiveserver2 fails to start when
hive.server2.authentication is set to KERBEROS
Key: HIVE-17207
URL: https://issues.apache.org/jira/browse/HIVE-17207
Project: Hive
Issue Type: Bug
Components: Authentication
Affects Versions: 2.2.0
Reporter: Rey Rey Chang
The logic in getAuthTransFactory() is flawed, as it will always "Unsupported
authentication type" error when authTypeStr is set to KERBEROS.
inside HiveAuthFactory class.
