    val conn = DriverManager.getConnection("jdbc:hive2://hadoop000:10000/default", "hadoop", "")

    val pstat = conn.prepareStatement("SELECT track_time, url, session_id, referer, ip, end_user_id, city_id FROM page_views WHERE city_id = -1000 limit 10")

    val rs = pstat.executeQuery()

    while (rs.next()) {

      println("track_time: " + rs.getString("track_time")

        + ", url: " + rs.getString("url")

        + ", end_user_id: " + rs.getString("end_user_id")

        + ", city_id: " + rs.getString("city_id"))



    }

    rs.close()

    pstat.close()

    conn.close()

  }
