1. There is a problem with the downloaded Hadoop/bin,

Refound some winutil.exe related to Hadoop/bin, and then replaced the old one and tried again. It was really successful!!!

Make sure the version is similar!!!

My Hadoop version of Linux is 3.1.4. Later, when connecting, I need to configure windows, which is 2.6.0. Then I keep reporting errors, so I changed it to 3.0. Be sure to choose a version similar!!!

2. Add static code blocks

static {
        try {
            System.load("D:\\install\\winutils-master\\winutils-master\\hadoop-3.0.0\\bin\\hadoop.dll");
            //We recommend using the absolute address, the path to the hadoop.dll file in the bin directory
        } catch (UnsatisfiedLinkError e) {
            System.err.println("Native code library failed to load.\n"+ e);
            System.exit(1);
        }
    }
