----------------------------------
Summary: Implement kill query in multiple HS2 environment
Key: HIVE-23084
URL: https://issues.apache.org/jira/browse/HIVE-23084
Project: Hive
Issue Type: Improvement
Components: HiveServer2
Reporter: Peter Varga
Assignee: Peter Varga
KILL <queryId|querytag> command was implemented in:
* https://issues.apache.org/jira/browse/HIVE-17483
* https://issues.apache.org/jira/browse/HIVE-20549
But it is not working in an environment where service discovery is enabled and
more than one HS2 instance is running (except for manually sending the kill
query to all HS2 instance).
Solution:
* If a HS2 instance can't kill a query locally, it should post a kill query
request to the Zookeeper
* Every HS2 should watch the Zookeeper for kill query requests and if its
running on that instance kill it
* Authorization of kill query should work the same
