启动ThriftJDBCServer:

cd $SPARK_HOME/sbin
start-thriftserver.sh &

 

使用jdbc访问ThriftJDBCServer代码段：

    Class.forName("org.apache.hive.jdbc.HiveDriver")

    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()
  }
