…he#3077) Closes apache#3069 # Rationale for this change When a catalog is explicitly configured with `type: hive` but `uri` is missing in `.pyiceberg.yaml`, the CLI currently fails with a raw `KeyError('uri')`, which is surfaced as just: `'uri'` ```bash ❯ cat .pyiceberg.yaml catalog: my_hive_catalog: type: hive warehouse: warehouse_loc ❯ uv run pyiceberg --catalog my_hive_catalog list 'uri' ``` It's confusing for users because the command appears to return an identifier-like value instead of a configuration error. This change adds explicit validation for required catalog properties when the catalog type is already specified (e.g. `hive`, `rest`, `sql`), so users get a clear actionable error message instead. ## Are these changes tested? Yes. - Added a CLI regression test for `--catalog <name> list` with `type: hive` and missing `uri` - Verified the error output contains a helpful `URI missing...` message and no longer prints `'uri'` ## Are there any user-facing changes? Yes. Users now see a clear error message (for example): `URI missing, please provide using --uri, the config or environment variable PYICEBERG_CATALOG__<CATALOG_NAME>__URI` instead of a raw `'uri'` error when `type: hive` is configured without `uri`.
