How Do I Do If the Flink Job Status on the MRS Console Is Inconsistent with That on Yarn?

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: Terminate the job whose launcherJob cannot be found. The status of the job submitted later will be updated.
