centos 6.5 中eclipse编辑HDFS Exception in thread "main" java.lang.NoClassDefFoundE

[qq_35801841]

我使用的是centos 6.5 ，eclipse ，maven 。
用maven来管理项目，新键maven项目，导入了相关架包 ；测试代码如下


package www.ibeifeng.com.hadoop.src;

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

public class HDFStest {

/**
* @param args
* @throws IOException
*/
public static void main(String[] args) throws Exception {
// TODO Auto-generated method stub

//core-site.xml hdfs-site.xml ...
Configuration conf = new Configuration();

//get fileSystem
FileSystem fileSystem = FileSystem.get(conf);

System.out.print(fileSystem);

}

}


报错如下：
Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/hadoop/conf/Configuration
at www.ibeifeng.com.hadoop.src.HDFStest.main(HDFStest.java:16)
