通过java连接到远程Hadoop集群（CDH4）

我有一个遥远的Hadoop机器集群Cloudera CDH4。我正试着从我的电脑上运行一个pig脚本。下面是我的JAVA代码：

import org.apache.pig.ExecType;
import org.apache.pig.PigServer;
import org.apache.pig.backend.executionengine.ExecException;
import org.apache.pig.data.Tuple;

public class TestPig {

public static void main(String args[]){

    PigServer pigServer;
    try {

        /** On définit les propriétés */
        Properties props = new Properties();

        props.setProperty("fs.default.name", "hdfs://master.node.ip.adress:8020");
        props.setProperty("mapred.job.tracker", "master.node.ip.adress:8021");





        System.setProperty("javax.xml.parsers.DocumentBuilderFactory", "com.sun.org.apache.xerces.internal.jaxp.DocumentBuilderFactoryImpl");

        /** mapreduce mode */
        pigServer = new PigServer(ExecType.MAPREDUCE, props);

        /** pig script's path */
        pigServer.registerScript("/user/admin/data/script.pig");

        /** printing the pig script's output */
        Iterator<Tuple> results = pigServer.openIterator("A");
        while(results.hasNext())
            System.out.println(results.next().toDelimitedString("\t"));


    } 
    catch (ExecException e) {   e.printStackTrace(); } 
    catch (IOException e) { e.printStackTrace(); }

}
}

我在互联网上搜索解决方案，但没有找到任何有效的方法

你有办法解决这个问题吗

谢谢。

你解决了吗？
