> 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
