使用JDBC连接和操作hive（hiveserver2）

第一步：创建项目 并导入hive相关jar包

第二步：编写代码如下：

import java.sql.Statement;
import java.sql.DriverManager;
import org.apache.tools.ant.taskdefs.Echo;

public class TestHive2 {
private static String driverName = "org.apache.hive.jdbc.HiveDriver";
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:hive2://192.168.222.3:10000/default", "hive", "");
    Statement stmt = con.createStatement();
    String sql = "SELECT * FROM people_new";    
    System.out.println("Running: " + sql);
    res = stmt.executeQuery(sql);
    while (res.next()) {
      System.out.println("id: "+String.valueOf(res.getString(1)) + "\t" + "name: "+String.valueOf(res.getString(2)) + "\t" + "hobby: "+String.valueOf(res.getString(3)));
      System.out.println("\n");
    }
  }
}

第三步：运行结果如下：
