Eclipse在Windows上启动的Java客户端无法连接到远程Hadoop

Question

我无法将我在Windows上由Eclipse启动的Java客户端连接到我的远程hdfs服务器。

我的hdfs服务器使用Hadoop 2.6.0在Cloudera Express 5.12.1上运行。 它适用于mac os但我在Windows上遇到以下错误：

Exception in thread "main" java.io.EOFException: End of File Exception between local host is: *HOST_IP*; destination host is: *DESTINATION_IP*:8020; : java.io.EOFException; For more details see:  http://wiki.apache.org/hadoop/EOFException
    at sun.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method)

这是我的java客户端代码：

package wordcount;

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

public class Main {
    public static void main(String[] args) throws Exception {
      InsertFile();
    }

    public static void InsertFile() throws Exception
    {
        Configuration conf = new Configuration();
        conf.set("fs.defaultFS", "hdfs://niko:8020");
        FileSystem fs = FileSystem.get(conf);
        FileStatus[] fsStatus = fs.listStatus(new Path("/"));
        for(int i = 0; i < fsStatus.length; i++) {
            System.out.println(fsStatus[i].getPath().toString());
        }
    } 
}

和我用于Maven的pom.xml文件：
