What Should I Do If the Flink Job Status on the MRS Console Is Inconsistent with That on YARN?

Question:

What should I do if the Flink job status on the MRS Console is inconsistent with that on YARN?

Answer:

To save storage space, you can modify the YARN configuration item yarn.resourcemanager.max-completed-applications to reduce the number of historical job records stored on YARN. Flink jobs are long-term jobs. The realJob is still running on Yarn, but the launcherJob has been deleted. As a result, the launcherJob cannot be found on Yarn, and the job status fails to be updated.

Stop the jobs where launcherJob cannot be found. The statuses of jobs submitted later will be updated.
