java - 无法连接到hive server2(SQL异常、thrift传输异常等)

Question

我们尝试使用 JAR 连接到 hive server2 数据库:

1. hadoop-common-2.7.1.2.3.2.0-2950.jar
2. hive-jdbc-1.2.1.2.3.2.0-2950-standalone.jar

我们将这 2 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，我们收到如下错误

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？

Answer 1

错误 72 是一个错误的 url 问题。您的 hive2 服务器是否以 HTTP 模式运行？

HiveServer2 以 HTTP 模式运行时的连接 URL 为:-

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为 10001。

您可以尝试以下网址吗:

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