   > The fix looks good to me. But could you elaborate a bit more in the pr description's `Why are the changes needed` section.
   > 
   > If I understand the issue and this fix correctly, the reason why some appId is called multiple times is that:
   > 
   > ```
   > When some appIds' removeResource took too much time, the `expiredAppCleanupExecutorService` in ShuffleTaskManager
   > would check and detect the same appId is expired multiple times. Therefore the same appId might be added to `expiredAppIdQueue` multiple time.
   > ```
   
   Done. Thanks your describe.
