tillrohrmann opened a new pull request #7565: [FLINK-11400] Linearize leadership operations in JobManagerRunner URL: https://github.com/apache/flink/pull/7565 ## What is the purpose of the change Introduce a leadershipOperation future in the JobManagerRunner. This future is completed whenever a leadership operation (granting or revoking leadership) has been fully completed. All subsequent leadership operations wait for their predecessors to complete before they are processed. This guarantees that the JobMaster is properly shut down and there cannot be a race condition between revoking and granting leadership. This PR is based on #7564. ## Verifying this change - Added `JobManagerRunnerTest#testConcurrentLeadershipOperations` ## 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: (yes) - The S3 file system connector: (no) ## Documentation - Does this pull request introduce a new feature?
