**Search before asking** - [x] I searched in the [issues](https://github.com/apache/paimon/issues) and found nothing similar. **Paimon version** master @ 526b91f09 (2.1-SNAPSHOT) **Compute Engine** Engine-agnostic (core `FileIO`); surfaces in any Flink/Spark/Hive catalog on `obs://`. **Minimal reproduce step** 1. Create a catalog with `warehouse = 'obs://<bucket>/warehouse'`, `fs.obs.endpoint` and `fs.obs.security.provider`, without static access/secret keys. 2. Any table operation fails with `UnsupportedSchemeException: Could not find a file io implementation for scheme 'obs' in the classpath.` `OBSLoader.requiredOptions()` declares `fs.obs.access.key` and `fs.obs.secret.key`. Required options are a selection gate (`FileIOLoader.requiredOptions()` Javadoc): when one is absent, `FileIO.get()` discards the loader and falls back to `HadoopFileIO`, which cannot resolve `OBSFileSystem` — it lives in the plugin-only classloader. **What doesn't meet your expectations?** hadoop-huaweicloud authenticates without static keys, through `fs.obs.security.provider` (`IObsCredentialsProvider`, e.g. ECS agency) or a Hadoop credential provider. Those configurations should route through the bundled OBS plugin instead of being gated out. `fs.obs.endpoint` should stay required: `DefaultOBSClientFactory` reads it without a default. **Anything else?** The same defect was reported and fixed for S3 in #8674 / #8679. **Are you willing to submit a PR?** - [x] I'm willing to submit a PR! -- This is an automated message from the Apache Git Service.
