spark Structured报错解决

报错，不想看原因的直接去解决方案试试

Exception in thread "main" java.lang.IllegalArgumentException: Pathname /C:/Users/Administrator/AppData/Local/Temp/1/temporary-611514af-8dc5-4b20-9237-e5f2d21fdf88/metadata from hdfs://master:8020/C:/Users/Administrator/AppData/Local/Temp/1/temporary-611514af-8dc5-4b20-9237-e5f2d21fdf88/metadata is not a valid DFS filename.

看报错信息好像是要赋权，路径不存在，但是这个路径有点古怪

hdfs://master:8020/C:/Users/Administrator/AppData/Local/Temp/1/temporary-611514af-8dc5-4b20-9237-e5f2d21fdf88/metadata is not a valid DFS filename

按道理不应该出现C:/。。。。这个是我本地的一个地址，但是却拼接到了hdfs文件系统下，应该是什么配置的有问题
顺着报错信息

只需要checkpointRoot修改就行这个地址来源于checkpointLocation
org.apache.spark.sql.streaming.StreamingQueryManager#createQuery

也就是说直接改变“checkpointLocation”的值就行

解决方案

在start之前设置

            .option("checkpointLocation", "file:///D:\\applicationfiles\\data\\kafka")

解决，完美
环境问题，在windows下有些默认配置会失效
