   ### 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：
