dawidwys opened a new pull request #10850: [FLINK-15519][configuration] Preserve logs from BashJavaUtils and make them part of TM logs URL: https://github.com/apache/flink/pull/10850 ## Brief change log We build a separate jar for BashJavaUtils with bundled log4j classes and a configuration that logs to the stdout. Using this jar we run the utility to capture the output. Out of the last line we extract jvm parameters. The rest we pass as an environment variable (INHERITED_LOGS) to the TaskManager process. As part of the EnvironmentInformation printing we log whatever was passed through the INHERITED_LOGS in the TM/JM process. ## Verifying this change * BashJavaUtilsITCase should still run * Start a taskmanager process, see the additional logs from the BashJavaUtils at the very top. ## 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?
