melin commented on SPARK-43338:
-------------------------------

kyuubi verified it: 
[https://kyuubi.readthedocs.io/en/v1.7.1-rc0/connector/spark/hive.html]
 
kyuubi is implemented based on HiveSessionCatalog. If there are huid tables in 
the hive database, another Hudi catalog needs to be registered. The same hms 
has two catalognames, which does not meet my requirements.
 

> Support  modify the SESSION_CATALOG_NAME value
