What happened

1, First, create a Hive data source

2, Edit the data source and find that the principal field is not displayed.

3，The connection test shows the following error message：

2025-08-12 10:04:52.808 WARN [qtp1869116781-5208] o.a.h.j.HiveConnection:[237] - Failed to connect to 192.168.11.231:10000

To resolve the above issue, The principal field needs to appear in the JDBC connection parameter input box.

4, Click the connection test again, and the following error appears:

What you expected to happen

The Hive and Spark data source information can be displayed normally, and the tests pass.

How to reproduce

1, First, create a Hive data source
2, Edit the data source and find that the principal field is not displayed.
3, Click the connection test
