YARN-11504. [Addendum] [Federation] YARN Federation Supports Non-HA mode

[yl09099]

Description of PR

When I was submitting (#5716) the PR, I found that junit reported an error, I took a closer look at this piece of code, and we should consider the logic for compatibility with HA

How was this patch tested?

For code changes:

• Does the title or this PR starts with the corresponding JIRA issue id (e.g. 'HADOOP-17799. Your PR title ...')?
• Object storage: have the integration tests been executed and the endpoint declared according to the connector-specific documentation?
• If adding new dependencies to the code, are these dependencies licensed in a way that is compatible for inclusion under ASF 2.0?
• If applicable, have you updated the LICENSE, LICENSE-binary, NOTICE-binary files?

@yl09099 Thank you for your feedback! Upon reviewing the code, I found that we execute the specified logic in non-HA mode. However, when HA is enabled, it should remain consistent with the original logic. Merged Into trunk.
