   > @flyrain: Why do we need to have a different HiveClientPool? Do these pools have a different configuration?
   
   Yes, it needs different config(`metastore.catalog.default`). 
   
   Once a client pool is created and cached, we don't reset its default catalog, so we can never visit the second catalog with the same uri. For example, `ClientPool1(uri1, catalog1)` is cached and always be used, but we need another one `ClientPool1(uri1, catalog2)` to visit the second catalog.
