The possible causes and solutions are as follows:
- After you purchase a DLI queue and submit a SQL job for the first time, wait for 5 to 10 minutes. After the cluster is started in the background, the submission will be successful.
- If the network segment of the queue is changed, wait for 5 to 10 minutes and then submit the SQL job immediately. After the cluster is re-created in the background, the submission is successful.
- The queue is idle for more than one hour, and background resources have been released. You must wait for 5 to 10 minutes and then submit the SQL job. After the cluster is restarted in the background, the submission will be successful.
