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, the Yarn configuration item yarn.resourcemanager.max-completed-applications is modified 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. This problem is fixed in the 2.1.0.6 patch.

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