我正在运行一个 flink emr 作业并得到以下结果：

长时间运行的 flink 纱线应用程序已启动并运行，我已经根据 https://docs.aws.amazon.com/emr/latest/ReleaseGuide/flink-configure.html 配置了具有高可用性的 emr 集群。
我还尝试通过flink run /usr/lib/flink/examples/batch/WordCount.jar运行示例批处理程序，我可以在 Web UI 中看到成功完成。
根据此错误，我是否可能缺少其他配置？
根据堆栈跟踪，看起来您已经将作业配置为使用MemoryStateBackend。配置此状态后端时，还可以指定检查点和保存点路径。配置这些路径时，指定模式hdfs://(或受支持且要使用的任何其他分布式文件系统(非常重要，因为系统需要知道要使用哪个Filesystem。而不是将路径指定为my/checkpoint/path，它应该是hdfs://my/checkpoint/path。
