我正在尝试使用hdfs创建一个目录，我的hadoop集群没有在localhost上运行，而是在另一个网络上运行。请告诉我如何正确连接。我使用以下代码连接到hdfs：

import java.io.BufferedInputStream;
    import java.io.IOException;

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

    public class HadoopJava {

        public static void main(String[] args) throws IOException {

            HadoopJava hadoopJava = new HadoopJava();
            hadoopJava.mkdir("/home/anoop/javamkdir");
        }

        public void mkdir(String directory) throws IOException {

            Configuration obj = new Configuration();
            obj.set("fs.default.name", "hdfs://10.111.214.124:50070");

            FileSystem fs = FileSystem.get(obj);
            Path path = new Path(directory);
            fs.mkdirs(path);
            System.out.println("created");
            fs.close();

        }
    }

错误跟踪如下：
