我是hadoop新手。我使用的是ubuntu，安装了hadoop、hive和pig。我正在尝试用java创建一个接口来获取配置单元查询并在后台执行它。
我正在使用ide eclipse-mars
源代码

package com.soniya.demo2;

    import java.sql.SQLException;
    import java.sql.Connection;
    import java.sql.ResultSet;
    import java.sql.Statement;
    import java.sql.DriverManager;

    public class TestJdb
    {
      private static String driver = "org.hadoop.apache.hive.jdbc.HiveDriver";

      /**
       * @param args
       * @throws SQLException
       */
      public static void main(String[] args) throws SQLException {
          try {
          Class.forName(driver);
        } catch (ClassNotFoundException e) {
          e.printStackTrace();
          System.exit(1);
        }

        Connection connect = DriverManager.getConnection("jdbc:hive2://:16074/default","","");
        Statement state = connect.createStatement();
        String tableName = "test";
        state.executeQuery("drop table " + tableName);
        ResultSet res = state.executeQuery("create table " + tableName + " (key int, value string)");

       // Query to show tables
        String show = "show tables";
        System.out.println("Running show");
        res = state.executeQuery(show);
        if (res.next()) {
          System.out.println(res.getString(1));
        }

        // Query to describe table
        String describe = "describe " + tableName;
        System.out.println("Running describe");
        res = state.executeQuery(describe);
        while (res.next()) {
          System.out.println(res.getString(1) + "\t" + res.getString(2));
        }

      }
    }

我得到以下错误

java.lang.ClassNotFoundException: org.hadoop.apache.hive.jdbc.HiveDriver
        at java.net.URLClassLoader.findClass(URLClassLoader.java:381)
        at java.lang.ClassLoader.loadClass(ClassLoader.java:424)
        at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:331)
        at java.lang.ClassLoader.loadClass(ClassLoader.java:357)
        at java.lang.Class.forName0(Native Method)
        at java.lang.Class.forName(Class.java:264)
        at com.soniya.demo2.TestJdb.main(TestJdb.java:21)

帮我解决这个问题。我已经包括了像hivejdbc、hadoop common这样的jar文件，但它不起作用，还尝试了hivelib jar文件，但仍然出现同样的错误。提前谢谢
