Research direction
Start with the failing test METADATA-036 — getColumns with null catalog returns columns from every catalog in ONE request [sea] in the coverage PR diff under tests/, then compare the intended behavior with databricks/databricks-jdbc PR #1580. Done means the Node.js driver returns cross-catalog columns for a NULL catalog request in one request and the conformance test turns green.

Description
Summary
Surfaced by the multi-language coverage fan-out while conformance-testing these SPEC-IDs against databricks/databricks-sql-nodejs. Each finding is committed as an expected-failure (xfail) test in the coverage PR — the test asserts the CORRECT (post-fix) behavior and stays red until THIS driver (databricks/databricks-sql-nodejs) is fixed, then flips green as a tripwire.
Findings
- METADATA-036 [sea]: SEA getColumns with a NULL catalog never returns: kernel metadata path fails with "Statement execution timed out" after ~10min, instead of one all-catalogs columns request returning cross-catalog rows (Thrift conforms with a single GetColumns RPC)
- failing test:

Context
- The behavior was first fixed in a DIFFERENT driver — reference PR: https://github.com/databricks/databricks-jdbc/pull/1580 — which seeded the shared language-neutral spec. This issue tracks the same conformance gap in databricks/databricks-sql-nodejs; the reference PR is for cross-referencing the intended behavior, NOT a change to this repo.
- Coverage PR carrying the reproducing xfail test(s): https://github.com/databricks/databricks-driver-test/pull/1081
