Hi @kaichiachen, thanks for taking over the Jira.

Although we removed the default queue configuration, we can still achieve the same behavior by setting the fixed rule in the end of placement rules. I'm in favor of adding such an example under the deprecated config.

For example, this explanation looks pretty good to me.

Thanks @chenyulin0719 ! I agree that we should provide guidance on configuring the desired queue once this configuration is no longer available. The official documentation includes a section elaborating how to configure the desired queue name: https://yunikorn.apache.org/docs/next/user_guide/placement_rules#fixed-rule
I think we can leverage it and add a hyperlink to the deprecated configuration. You can check my latest screenshot, thanks!

+1 LGTM, adding hyperlink make sense to me.

@kaichiachen The result layout is correct. This is a very nitpicky change request.
