我正在通过Flink仪表板向具有三个任务管理器的群集提交Flink作业。当我将Parallelism设置为1（默认值）时，一切都按预期运行。但是，当我将Parallelism增加到大于1的任何值时，作业将失败并带有例外，
java.io.FileNotFoundException: /tmp/flink-io-f91d7812-a411-4b58-a891-c9be1cde91da/08caeac37d6b8351daf6a3eb123a473106c56381b101f3e5d9704df9f78406a2.0.buffer (No such file or directory)

我已经在我的Flink作业上启用了检查点，每10秒就有一次“完全一次”重试策略。这是我的检查点配置，
env.setStateBackend(new RocksDBStateBackend(props.getFlinkCheckpointDataUri(), true));
env.enableCheckpointing(10000, EXACTLY_ONCE); //10 seconds
CheckpointConfig config = env.getCheckpointConfig();
config.enableExternalizedCheckpoints(CheckpointConfig.ExternalizedCheckpointCleanup.RETAIN_ON_CANCELLATION);
除了在仪表板中提交作业时输入2之外，我是否应该配置其他内容？
编辑：如果我禁用检查点并上传作业，它将运行而不会出现任何错误。
