> This is another step to remove Hive client usage in `HiveSessionState`.
> Different sessions are sharing the same class loader, and thus, `metadataHive.addJar(path)` basically loads the JARs for all the sessions. Thus, no impact is made if we move `addJar` from `HiveSessionState` to `HiveExternalCatalog`.
