Question

我们尝试使用JAR连接到hive server2数据库：

Hadoop的共2.7.1.2.3.2.0-2950.jar
蜂房JDBC-1.2.1.2.3.2.0-2950-standalone.jar

我们将这两个jar集成到Eclipse项目中，连接到hive数据库的代码是：

Connection con=null;
    try {
        Class.forName("org.apache.hive.jdbc.HiveDriver");
        StringBuffer jdbcConnectionString = new StringBuffer();
        jdbcConnectionString.append("jdbc:hive2://10.205.64.70:10000/default");
        con = DriverManager.getConnection(jdbcConnectionString.toString(),"********","********");
    } catch (ClassNotFoundException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

但是当我们执行时，我们得到如下错误

java.sql.SQLException: Could not open client transport with JDBC Uri: jdbc:hive2://10.205.64.70:10002/imsone: Invalid status 72

有人可以帮我解决这个问题吗？

错误72是一个糟糕的网址问题。您的hive2服务器是否以HTTP模式运行？

HiveServer2在HTTP模式下运行时的连接URL是： -

jdbc:hive2://<host>:<port>/<db>;transportMode=http;httpPath=<http_endpoint>

其中： - 是hive-site.xml中配置的相应HTTP端点。默认值为cliservice。

HTTP传输模式的默认端口是10001。

你可以尝试下面的网址：

jdbc:hive2://10.205.64.70:10001/default;transportMode=http;httpPath=cliservice

无法连接到hive server2（SQL异常，thrift传输异常等）
