使用JAVA从HDFS中的一个目录复制到HDFS中的另一个目录

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

public class HDFSFileCopy {
    public static void main(String[] args) {
        String sourcePath = "hdfs://localhost:9000/source_directory";
        String destinationPath = "hdfs://localhost:9000/destination_directory";

        Configuration conf = new Configuration();
        try {
            FileSystem fs = FileSystem.get(conf);
            Path source = new Path(sourcePath);
            Path destination = new Path(destinationPath);

            fs.copyFromLocalFile(false, true, source, destination);
            System.out.println("File copied successfully from " + sourcePath + " to " + destinationPath);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}
