derrickHu0702 opened a new issue, #8603:
URL: https://github.com/apache/gravitino/issues/8603
### Version
0.9.0
### Describe what's wrong
When using the Gravitino Python client, calling
gravitino_client.load_catalog("catalog_name") on a catalog that is supposed to
be of a relational type (e.g., Hive) results in a NotImplementedError:
Unsupported catalog type: Type.RELATIONAL.
This is counter-intuitive because relational catalogs are a supported
feature. The error message suggests that the RELATIONAL type enum itself is not
recognized during the loading process, which might point to an issue in the
client-side implementation for handling this catalog type. The creation of the
relational catalog might succeed, but any subsequent attempt to load it fails.
The implementation of dto_converters.py::to_catalog seems to be missing a
case for Catalog.Type.RELATIONAL. It likely has handlers for other types like
FILESET or MODEL, but the logic to instantiate a RelationalCatalog object on
the client side is either missing or failing, leading to the
NotImplementedError.
