hive jdbc方式查询出现: Table not found 错误

在弄一个项目，需要采用编成的方式从hive中查询数据，但是没有成功，说Table not found.。但我用hive shell 能够查到数据，而且hive的表是存在hdfs中，之前数据是通过hive shell 从hdfs中导入的。
求各位帮我分析原因并提出解决方案，谢谢！
demo代码如下：
package com.checkking.hive;
import java.sql.SQLException;
import java.sql.Connection;
import java.sql.ResultSet;
import java.sql.Statement;
import java.sql.DriverManager;
public class HiveJdbcClient {
  private static String driverName = "org.apache.hadoop.hive.jdbc.HiveDriver";
  /**
* @param args
* @throws SQLException
   */
  public static void main(String[] args) throws SQLException {
      try {
      Class.forName(driverName);
    } catch (ClassNotFoundException e) {
      // TODO Auto-generated catch block
      e.printStackTrace();
      System.exit(1);
    }
   
    Connection con = DriverManager.getConnection("jdbc:hive://", "", "");
    Statement stmt = con.createStatement();
   
   // stmt.executeQuery("use default");
    ResultSet res  = stmt.executeQuery("select count(*) from default.log_hive_table where dt='20130317'");
   
    if (res.next()) {
      System.out.println(res.getInt(1));
    }
      con.close();
  }
}
报错：

demo代码如下：
Java code?1234567891011121314151……
Hive Thrift Server 启动了吗？
在HIVE所在的LINUX SHELL中输入
[hadoop@xxx bin]# hive --service hiveserver 50031
Starting Hive Thrift Server //启动成功
Connection con = DriverManager.getConnection("jdbc:hive://", "", "");
//con 改成以下，以便多CLIENT访问
Connection con = DriverManager.getConnection(
                     "jdbc:hive://HiveServier的IP地址:50031/default", "", "");
        

            检查启动了hiveserver服务没，貌似还要检查metastore服务是否开启。
还有，官方wiki的sample看了么？那个是没问题的！！你仔细检查一下！
