这个问题主要原因可以看一下后边那个报错

Caused by: java.io.FileNotFoundException: E:/bigdata/hdfs_temp/mapred/local/localRunner/Ruby%20Wang/jobcache/job_local1561914882_0001/attempt_local1561914882_0001_m_000000_0/output/file.out.index 

说是文件找不到异常
根据大佬的解析 一个是路径问题 一个是没有这个文件
这里发现这个文件是自动创建的 那么就是路径问题

众所周知
hadoop路径里是不能有空格的 然而这个自创的路径里有空格 于是就要更改这个路径

大佬解决办法:Hadoop本地运行出现:Caused by: java.io.FileNotFoundException:D:/tmp/hadoop-win2010/mapred/local/

具体:
