FANNG1 opened a new issue, #11578: URL: https://github.com/apache/gravitino/issues/11578
**Version** main branch **Describe what's wrong** When Spark Lance uses Gravitino Lance REST (`impl=rest`) against a namespace-backed table, the write/commit path can call `describeTable(version=N)` instead of latest-only `describeTable()`. Gravitino Lance REST currently rejects that request with: `Unsupported: Describing specific table version is not supported.` As a result, INSERT/commit on existing tables fails even though `describeTable()` without a version works. **Error message and/or stacktrace** `Unsupported: Describing specific table version is not supported.` **How to reproduce** 1. Configure a Lance catalog in Gravitino with `impl=rest` and create a table. 2. Use Spark Lance against the Gravitino REST endpoint with a namespace-backed table. 3. Run `INSERT INTO` on an existing table. 4. During commit, Lance Spark calls `namespace.describeTable(version=1)` and the request fails. **Additional context** - `describeTable()` without a version works. - The failure only appears when the version is non-empty. - This looks like a cross-project compatibility issue between Gravitino Lance REST and Spark Lance's versioned commit path. - If versioned describe is intentionally unsupported, Spark Lance may need to avoid passing `version` in this path or gate the behavior more carefully. -- This is an automated message from the Apache Git Service.
