Hadoop Hbase访问被拒绝例外

Question

我想访问已与Hbase表同步的凤凰表。我写了一些jdbc代码来访问Phoenix表中的数据，但是由于启用了护林员策略，我遇到了访问被拒绝的异常。

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");

我得到的错误消息是：

org.apache.hadoop.hbase.security.AccessDeniedException: org.apache.hadoop.hbase.security.AccessDeniedException: Insufficient permissions for user ‘saurav_bilung',action: scannerOpen, tableName:SYSTEM.STATS, family:0, column: GUIDE_POSTS_ROW_COUNT

“登陆”用户已被授予通过护林员执行所有任务的权限，但仍然收到错误消息，显示为“权限不足”。我想以“登陆”用户身份创建连接。在这里需要帮助

Answer 1

根据您的错误消息，似乎是它正在尝试为您的用户“ saurav_bilung”而不是“着陆”用户进行身份验证。当您提交或运行代码时，您是否正在以“着陆”用户身份注册？另外，请确保您的用户和“登陆用户”有权访问SYSTEM.STATS表。让我知道怎么回事
