### Search before asking - [X] I had searched in the [issues](https://github.com/apache/dolphinscheduler/issues?q=is%3Aissue) and found no similar issues. ### What happened Suppose there are three workgroups, namely default1, default2, default3. When all the machines in the workgroup default1 go down, the high-priority tasks of the default1 workgroup will always be retried in the queue, trying to find machines to execute, other workgroups The low-priority tasks will be blocked all the time. ### What you expected to happen After all the machines in a work group are down, it will not block the scheduling of other work group tasks ### How to reproduce Divide the task distribution queue into two. When a task cannot find a work group, it is put into another queue, and the other queue is consumed by a dedicated thread.The code screenshot is as follows：  ### Anything else _No response_ ### Version 1.3.6 ### Are you willing to submit PR? - [X] Yes I am willing to submit a PR! ### Code of Conduct - [X] I agree to follow this project's [Code of Conduct](https://www.apache.org/foundation/policies/conduct) -- This is an automated message from the Apache Git Service.
