Spark3 & Hive3 inompatibility issue when use sparksql to query hive table stored as textfile about kyuubi

[github-actions]

Hello @hanson2021,
Thanks for finding the time to report the issue!
We really appreciate the community's efforts to improve Apache Kyuubi.

please fill in the missing Kyuubi Engine Configurations, especially, how do you configure hive metastore in spark-defaults.conf?

The components setup is unclear, I assume you are using the Spark Hive IsolatedClientLoader feature. And I can NOT reproduce on Spark master with the following configurations.

spark.sql.hive.metastore.version=3.1.2
spark.sql.hive.metastore.jars=maven

With a little more digging, I think the code path is already covered by Spark UT. HiveClientSuite

Additional feedback requires you to provide reproducible steps.

You mean replacing jars under $SPARK_HOME/jars? this is not a reasonable use case, any issues caused by such intrusive action are unpredicted.
