> Function-related `HiveExternalCatalog` APIs do not have enough verification
> logics. After the PR, `HiveExternalCatalog` and `InMemoryCatalog` become
> consistent in the error handling.
> For example, below is the exception we got when calling `renameFunction`.
> {noformat}
> 15:13:40.369 WARN org.apache.hadoop.hive.metastore.ObjectStore: Failed to get
> database db1, returning NoSuchObjectException
> 15:13:40.377 WARN org.apache.hadoop.hive.metastore.ObjectStore: Failed to get
