I am facing an error during hiverserver2 start as "

caught exception: ZooKeeper node /hiveserver2 is not ready yet

and when I debug more I see that there is no hiveserver2 instance in zookeeper.

Can someone tell me how to create znode name if hiveserver2 is not registered to znode?.

In general, ambari will create that znode by default. we dont need to create manually. logs shows that issue with sasl. we can still create znode manually after logging into zookeeper cli.
