由于我们长期以来一直面临上述错误，请给予帮助。 提前谢谢

主要的例外是：

Caused by: java.net.ConnectException: Connection refused

您正在打开连接，但此行中没有用户名/密码：

Connection con =DriverManager.getConnection("jdbc:hive2://localhost:10000/default","","");

---

请验证数据库的用户名和密码

谢谢你的及时回复。我已经从“hive default.xml.template”文件中添加了以下用户名和密码，但运气不好。仍在获取相同的错误日志。如果还缺什么，请告诉我。用户名：APP密码：mine Connection con=DriverManager.getConnection（“jdbc:hive2://localhost:10000/default”、“APP”、“mine”）；

Connection con =DriverManager.getConnection("jdbc:hive2://localhost:10000/default","","");
