Hi @vijaya inturi you can add multiple HS2 servers, and access them using Zookeeper discovery. On each call ZK will connect you to a random, alive HS2 instance. In a Kerberos environment the user who runs beeline needs a valid ticket, and has to insert the hive principal in the connect string. You can find beeline connection string samples here.

I have read in another coludera community thread that using dynamic service discovery has some issues https://community.cloudera.com/t5/Support-Questions/CDH-5-4-0-and-HiveServer2-High-Availability-via-ZooKeeper/td-p/33469 and i am working on setting up using HAProxy following a doc from cloudera which talks about setting LB for both impala and Hive https://docs.cloudera.com/runtime/7.0.2/tuning-hue/topics/hue-configure-hive-impala-for-ha-with-hue.html

My question is which one would you recommend and can you let me know the caveats..

Thanks

Rajesh
