我们正在用毛线织东西。我们正在执行灾难恢复测试，作为测试的一部分，我们手动终止了运行flink应用程序的其中一个节点。示例恢复后，应用程序进行了多次尝试，每次尝试都出现以下错误：

有人能告诉我们什么内容存储在hdfs中，如果这可以重定向到s3吗？
添加与检查点相关的设置：

StateBackend rocksDbStateBackend = new RocksDBStateBackend("s3://Path", true);
streamExecutionEnvironment.setStateBackend(rocksDbStateBackend)
streamExecutionEnvironment.enableCheckpointing(10000);
streamExecutionEnvironment.getCheckpointConfig().setCheckpointingMode(CheckpointingMode.EXACTLY_ONCE);
streamExecutionEnvironment.getCheckpointConfig().setMinPauseBetweenCheckpoints(5000);
streamExecutionEnvironment.getCheckpointConfig().setCheckpointTimeout(60000);
streamExecutionEnvironment.getCheckpointConfig().setMaxConcurrentCheckpoints(60000);
streamExecutionEnvironment.getCheckpointConfig().enableExternalizedCheckpoints(ExternalizedCheckpointCleanup.RETAIN_ON_CANCELLATION);
streamExecutionEnvironment.getCheckpointConfig().setPreferCheckpointForRecovery(true);
