【中文标题】%jdbc(hive) - 无法使用 JDBC Uri 打开客户端传输【英文标题】:%jdbc(hive) - Could not open client transport with JDBC Uri 【发布时间】:2019-06-08 06:00:46 【问题描述】:我正在尝试使用 Zeppelin 上的 JDBC 驱动程序运行一些配置单元查询。
当我运行这个命令时,%jdbc(hive)
我得到以下响应错误。
java.sql.SQLException: Could not open client transport with JDBC Uri: jdbc:hive2://localhost:10000: java.net.ConnectException: Connection refused (Connection refused)
以下是我的 hive-site.xml。

更新
我在下面的/tmp/root/hive.log
文件中找到。因此,根本原因必须在 hive-metastore。

【问题讨论】:
【参考方案1】:在您的配置中,HS2 与 Zeppelin 位于同一台机器上。那正确吗? 另外,你能从 Zeppelin 主机连接到 HS2 的端口吗? 测试:
telnet hive_host hive_port (default 10000)
在 hive jdbc 字符串中,通常在端口后有一个 '/' 用于连接数据库,你的是空的,我建议将此字符串更改为:
jdbc:hive2://$HIVE_HOST:$HIVE_PORT/DB
如果您在 DB 中不插入任何内容,HS2 将默认连接到数据库。
