### Describe the bug

According to the PR https://github.com/apache/spark/pull/42760, if the hive.metastore.token.signature parameter is not empty, we may also encounter authentication failures in Kyuubi.

1. Set the configuration bellow
```

hive.metastore.token.signature
HIVE_DELEGATION_TOKEN

```
3. Start kyuubi server with `hive`
4. Connet kyuubi with proxy user ，
5. Run sql `insert into test11 values('a');`

then the user will be `hive` to execute hdfs command

### Are you willing to submit PR?

- [X] Yes. I would be willing to submit a PR with guidance from the Kyuubi community to fix.
- [ ] No. I cannot submit a PR at this time.

Start by reproducing the failure with hive.metastore.token.signature set to HIVE_DELEGATION_TOKEN, a Kyuubi server started with Hive, a proxy-user connection, and the reported INSERT statement. Trace the GSS initialization and HDFS command identity, then verify that the proxy user rather than hive executes the command; no source file or test is named in the report.
