Eugene Chung created HIVE-23153:
-----------------------------------
Summary: deregister from zookeeper is not properly worked on
kerberized environment
Key: HIVE-23153
URL: https://issues.apache.org/jira/browse/HIVE-23153
Project: Hive
Issue Type: Bug
Components: HiveServer2
Reporter: Eugene Chung
Assignee: Eugene Chung
Attachments: Screen Shot 2020-04-08 at 5.00.40.png
Deregistering from Zookeeper, initiated by the command 'hive --service
hiveserver2 -deregister <hostname>', is not properly worked when HiveServer2
and Zookeeper are kerberized. Even though hive-site.xml has configuration for
Zookeeper Kerberos login (hive.server2.authentication.kerberos.principal and
keytab), it isn't used. I know that before executing the command, kinit with
hiveserver2 keytab would work. But as I said, hive-site.xml already has.

Plus, the result code of CuratorEvent from DeleteCallback is not checked. In
the case that kerberos login is not done, the code is -102
