如何通过编程方式获取HDFS和YARN版本？

import org.apache.hadoop.conf.Configuration;
import org.apache.hadoop.fs.FileSystem;

public class HDFSVersion {
    public static void main(String[] args) throws Exception {
        Configuration conf = new Configuration();
        FileSystem fs = FileSystem.get(conf);
        String version = fs.getUri().getVersion();
        System.out.println("HDFS Version: " + version);
    }
}

import org.apache.hadoop.conf.Configuration;
import org.apache.hadoop.yarn.api.records.YarnVersionInfo;

public class YARNVersion {
    public static void main(String[] args) {
        Configuration conf = new Configuration();
        String version = YarnVersionInfo.getVersion();
        System.out.println("YARN Version: " + version);
    }
}
