The GitHub Actions job "Nightly (beta)" on flink.git/master has failed. Run started by GitHub user github-actions[bot] (triggered by github-actions[bot]).
Head commit for run: 7b663bae4c512f6d32696ded52edbcb62a5b6554 / Martijn Visser <[email protected]> [FLINK-40074][tests] Avoid @TempDir cleanup race in SinkV2ITCase scaling test writerAndCommitterExecuteInStreamingModeWithScaling injected the checkpoint directory through JUnit's @TempDir. The class-shared MiniCluster keeps discarding checkpoint state asynchronously after the finished job returns its result, so JUnit's temp directory deletion races with that discard and intermittently fails with "Failed to delete temp directory" once the job is done, even though all test assertions pass. Manage the checkpoint directory explicitly and clean it up quietly with FileUtils#deleteDirectoryQuietly, which is safe against concurrent deletions and never lets a cleanup failure mask a real test failure.
