Myasuka commented on issue #10768: [FLINK-15012][checkpoint] Introduce shutdown to CheckpointStorageCoordinatorView to clean up checkpoint directory. URL: https://github.com/apache/flink/pull/10768#issuecomment-612656015 Refactor this PR with two commits: * Introduce `shutdown` to CheckpointStorageCoordinatorView to clean up checkpoint directory. * Introduce cleanup-storage-directories-recursively option to CheckpointConfig. We would not delete files recursively be default. However, as we might often meet "not empty" exception due to orphan or not-ready-to-discard files, we should provide option for users to remove directories recursively.
