Review Comment:
The behavior for `SHOW TABLES IN catalog_name` is to list the root
namespace. If the root namespace is not a supported namespace, it fails (I
tested a local HadoopCatalog). I think that is reasonable behavior: the `IN`
clause specifies the namespace to list. The multi-part identifier passed to the
`IN` clause is resolved and the current catalog is used if no catalog is
specified, but the current namespace is not used.
This test should run `SHOW TABLES IN catalogName.namespaceOne`, then run
`USE`, then run `SHOW TABLES`.
