TisonKun opened a new pull request #9880: [FLINK-14347][test] Filter out expected exception string in YARN tests URL: https://github.com/apache/flink/pull/9880 ## What is the purpose of the change Filter out expected exception string in YARN tests, especially `YARNSessionFIFOITCase.checkForProhibitedLogContents`. The instability reported in FLINK-14347 depends on whether or not `jobmanager.log` has been dumped on the verification. Given that the "forbidden" string is actually expected[1] I propose we add the next line into whitelist. Locally verify when `jobmanager.log` dumped we find the "forbidden" string and filter out with the exclusion of expected Exception. Received shutdown request from YARN ResourceManager [1] Specifically, we call `YarnClient#killApplication` in `YARNSessionFIFOITCase#runDetachedModeTest` which always causes a shutdown request. ## Verifying this change This change is itself about tests. ## Does this pull request potentially affect one of the following parts: - Dependencies (does it add or upgrade a dependency): (no) - The public API, i.e., is any changed class annotated with `@Public(Evolving)`: (no) - The serializers: (no) - The runtime per-record code paths (performance sensitive): (no) - Anything that affects deployment or recovery: JobManager (and its components), Checkpointing, Yarn/Mesos, ZooKeeper: (no) - The S3 file system connector: (no) ## Documentation - Does this pull request introduce a new feature?
