无法从checkpoint中恢复state

[sun]

你好，我有2个问题

1：每次重启服务，checkpoint的目录中chk-  总是从chk-1开始，chk-2 ........,没有从上次的编号开始

2：重启服务后，没有从checkpoint中恢复state的数据

下面是我的配置，我是在本地调试的，单机



final StreamExecutionEnvironment streamExecutionEnvironment = StreamExecutionEnvironment.createLocalEnvironmentWithWebUI(conf);

//            StateBackend stateBackend = new RocksDBStateBackend("hdfs://10.100.51.101:9000/flink/checkpoints",true);
            StateBackend stateBackend = new FsStateBackend("file:///flink/checkpoints");
//            StateBackend stateBackend = new MemoryStateBackend();
            streamExecutionEnvironment.setStateBackend(stateBackend);

            streamExecutionEnvironment.enableCheckpointing(1000);
            streamExecutionEnvironment.getCheckpointConfig().setCheckpointingMode(CheckpointingMode.EXACTLY_ONCE);
            streamExecutionEnvironment.getCheckpointConfig().setMinPauseBetweenCheckpoints(500);
            streamExecutionEnvironment.getCheckpointConfig().setCheckpointTimeout(60000);
            streamExecutionEnvironment.getCheckpointConfig().setMaxConcurrentCheckpoints(1);
            streamExecutionEnvironment.getCheckpointConfig()
                    .enableExternalizedCheckpoints(CheckpointConfig.ExternalizedCheckpointCleanup.RETAIN_ON_CANCELLATION);
