When start coordinator-server , got the exception: No FileSystem for scheme: hdfs

### Search before asking

- [x] I searched in the [issues](https://github.com/alibaba/fluss/issues) and found nothing similar.

### Description

fluss version: 0.7.0
server.yaml configured :

datalake.format: paimon
datalake.paimon.metastore: filesystem
datalake.paimon.warehouse: hdfs://lm1:8020/paimon/catalog

After starting all tablet-servers, when starting coordinator-server, an exception was reported: No FileSystem for scheme: hdfs

### Willingness to contribute

- [x] I'm willing to submit a PR!

Start by reproducing coordinator-server startup with the server.yaml settings shown in the issue, then trace how the configured filesystem warehouse is resolved. Check why the hdfs scheme has no available filesystem implementation. Done means coordinator-server starts successfully with the reported Paimon warehouse configuration.
