kl0u opened a new pull request #10115: [FLINK-14630] Re-enable Yarn tests to write job manager logs URL: https://github.com/apache/flink/pull/10115 ## What is the purpose of the change With [FLINK-14502](https://issues.apache.org/jira/browse/FLINK-14502) we changed how log property files are being discovered by the `YarnClusterDescriptor` and this resulted in Yarn tests not writing their job manager log files anymore. This made debugging a lot harder and next to impossible. This commit fixes this by introducing and exposing the utility method `Configuration setLogConfigFileInConfig(...)` in the `FlinkYarnSessionCli` which is responsible for discovering the log config file. This method is now used directly by the tests to simulate what the CLI does based on user-provided input. ## Verifying this change Running a test like the `YarnITCase` and seeing the log files being created in the `target` dir is sufficient to verify the validity of the change. ## Does this pull request potentially affect one of the following parts: - Dependencies (does it add or upgrade a dependency): (yes / **no**) - The public API, i.e., is any changed class annotated with `@Public(Evolving)`: (yes / **no**) - The serializers: (yes / **no** / don't know) - The runtime per-record code paths (performance sensitive): (yes / **no** / don't know) - Anything that affects deployment or recovery: JobManager (and its components), Checkpointing, Yarn/Mesos, ZooKeeper: (yes / **no** / don't know) - The S3 file system connector: (yes / **no** / don't know) ## Documentation - Does this pull request introduce a new feature?
