URL: https://github.com/apache/incubator-doris/issues/4795


   **Describe the bug**
   When `Load Job Task Queue` is filled, continue to submit more jobs to the 
queue will cause `RejectedExecutionException`, and the load job will be 
retried. But `callback.onTaskFailed` function does not catch the exception, 
that will cause re-submitting job failed, and status is not updated to failed.
   
   **To Reproduce**
   Steps to reproduce the behavior:
   1. set FE configuration: async_load_task_pool_size=30
   2. create a table
   3. create more than 60 broker load jobs, start them concurrently to fill the 
broker load job queue.
   4. See error
