org.apache.kyuubi.KyuubiSQLException: Invalid SessionHandle when multiple Kyuubi server is running

[yaroslavambrozyak]

Hi, I get Invalid SessionHandle error when I try to call REST API to execute the query or get the result. I am running Kyuubi on k8s and get the error only if I run multiple replicas, it does not appear if I run a single instance of Kyuubi server.
I noticed that error appears if a session is created on the first server but the request to execute a query goes to the second one.
I am using Kyuubi v.1.6.0 (master branch), using an external zookeeper. Do I miss some configuration?
Thanks

The shared state does not complete yet, you may need to use the client IP hash-based LB strategy to make sure one client always accesses the same Kyuubi instance for now.

Got it, thanks for a quick reply

Hi @pan3793, just want to check, is there any progress on this feature? Do you have an approx ETA? We are planning to have multiple Kyuubi instances in production

Any update on this thread?

AFAIK, the existing core developers do not put it in high priority, and it's an open-source and community-driven project, if anyone highly requires this feature, please feel free to send PR, I am happy to help review it.
