@Madhukar525722 Thank you for your effort in working on upgrading Hive 4, it seems you touched both the Spark engine/plugin modules and the Hive engine module, I would say it's IMPOSSIBLE to upgrade the Spark's built-in Hive to 4 at the current stage, all Kyuubi supported Spark versions(Spark 3.2 to 3.5 and 4.0 as of today) use Hive 2.3. So I think you are focusing on upgrading the Hive engine to Hive 4, right?

Thanks @pan3793 for the review. Now, I understood what I missed, I forgot about spark dependency of hive on 2.3.10 and 2.3.9. Yes, I was focusing on hive engine upgrade, I will upgrade hive jdbc.
