我想访问与 Hbase 表同步的 phoenix 表。我编写了一些 jdbc 代码来访问 Phoenix 表中的数据，但是由于启用了游侠策略，我得到了拒绝访问异常。

Class.forName("org.apache.phoenix.jdbc.PhoenixDriver");
Connection conn = DriverManager.getConnection(
                "jdbc:phoenix:abc1,abc2,abc3:2181:/hbase-unsecure","landing", "password");
System.out.println("Got connection !!!");
ResultSet rst = conn.createStatement().executeQuery("select * from EMP");

我收到错误消息：

“登陆”用户已被授予通过游侠执行所有任务的权限，但我仍然收到“权限不足”的错误消息。我想以“登陆”用户的身份创建连接。在这里需要帮助

根据您的错误消息，它似乎正在尝试为您的用户“saurav_bilung”而不是“登陆”用户进行身份验证。当您提交或运行您的代码时，您是作为“登陆”用户使用 sudo 吗？此外，请确保您的用户和“登陆”有权访问 SYSTEM.STATS 表。让我知道情况如何
