Error while running command to get file permissions : java.io.IOException: (null) entry in command string: null ls -F

Configure the path before modification:

//本地运行输入路径配置
TextInputFormat.addInputPath(job, new Path("file:///D:\\IdeaWorkSpace\\bigDate\\data\\sort\\sort_input"));

Causes and solutions

1. No specific path is specified. If there is only a single file, the path can be written to the specific file to the path
   as follows:

//本地运行输入路径配置
TextInputFormat.addInputPath(job, new Path("file:///D:\\IdeaWorkSpace\\bigDate\\data\\sort\\sort_input\\1.txt"));

2. If need to read multiple files in the file directory path and finally add \\*
   asTextInputFormat.addInputPath(job, new Path("file:///D:\\IdeaWorkSpace\\bigDate\\data\\sort\\sort_input\\*"));

//本地运行输入路径配置
TextInputFormat.addInputPath(job, new Path("file:///D:\\IdeaWorkSpace\\bigDate\\data\\sort\\sort_input\\*"));

So you can read the contents of all files under sort_input
