Review Comment:
   `tearDown()` unconditionally drops the same schema in the 
model/relational/fileset catalogs, but several tests only create the schema in 
one catalog (and `test_catalog_tag_operations` creates none). 
`BaseSchemaCatalog.drop_schema()` raises `NoSuchSchemaException` on missing 
schemas, so this teardown will fail the tests. Consider either creating the 
schema in all relevant catalogs in `setUp()` (and dropping in `tearDown()`), or 
catching/ignoring `NoSuchSchemaException` per catalog, or tracking which 
schemas were created before attempting to drop.

Review Comment:
   `tearDownClass()` does not call `super().tearDownClass()`. Since 
`IntegrationTestEnv.tearDownClass()` stops the Gravitino server when it was 
started by the test harness, skipping the superclass teardown can leave the 
server running and affect subsequent integration tests. Please call 
`super().tearDownClass()` (ideally in a `finally` block after your cleanup).

Review Comment:
   `multiple_locations_fileset_properties` is defined but never used in this 
test module, which adds noise and can confuse future maintenance. Consider 
removing it or adding a test case that actually exercises multi-location 
fileset properties.

Review Comment:
   `as_model_catalog()` now advertises a return type of `GenericModelCatalog`, 
but the docstring still refers to `ModelCatalog` (and uses a Java-style `{@link 
...}` reference). Please update the docstring to match the actual Python 
class/type to avoid confusion for API consumers and type-checkers.

Review Comment:
   The HDFS/Hive docker container created in `setUpClass()` 
(`cls._hdfs_container = HDFSContainer()`) is never closed. Other integration 
tests explicitly call `hdfs_container.close()` in `tearDownClass()` to avoid 
leaking containers/networks across test runs. Please close 
`cls._hdfs_container` during teardown (in `finally`) before calling 
`super().tearDownClass()`.

Review Comment:
   For MODEL/FILESET catalogs, other integration tests pass `provider=None` 
when using managed catalogs. Here `provider=""` is passed, which may round-trip 
as an empty provider value and break client-side validation (e.g., some catalog 
DTO validations require a non-blank provider). Consider using `provider=None` 
for managed model/fileset catalogs for consistency and to avoid empty-string 
edge cases.
