   > @BsoBird, have you considered using HiveCatalog (backed by HMS) instead of 
HadoopCatalog? Wonder if there were some restrictions or user specific 
use-cases.
   @deniskuzZ 
   Hi. We can't use HMScatalog to replace fsCatalog at the moment, because in 
our production environment, we are currently running multiple versions of 
HIVE/SPARK at the same time. HIVE3+SPARK serves some of the users, and HIVE4 
serves some others. But they need to share the same ICEBERG data.So, we have to 
choose a lightweight catalog for sharing data between different computing 
engines.
