我想在一台机器上本地运行Spark结构化流作业。不幸的是，当在处理数据时中止作业时，无法从中止的作业中恢复（操作失败，并显示以下日志）。
（如果流作业在等待新数据时中止，则恢复工作正常，并且可以正确读取检查点数据）。
java.lang.IllegalStateException: Error reading delta file, spark structured streaming with kafka表示原因可能是因为使用本地文件系统而不是HDFS来存储检查点，但是在这种情况下，检查点数据存储在HDFS中。
java.lang.IllegalStateException: Error reading delta file hdfs://localhost:9000/user/test/state/0/117/1.delta of HDFSStateStoreProvider[id = (op=0,part=117),dir = hdfs://localhost:9000/user/test/state/0/117]: hdfs://localhost:9000/user/test/state/0/117/1.delta does not exist

如果有人知道原因，那就太好了。
