我想访问同步到hbase表的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ranger策略，我遇到了拒绝访问异常。

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");

我得到的错误消息如下：

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ranger执行所有任务的权限，但我仍然收到错误消息“权限不足”。我想作为“登陆”用户创建连接。这里需要帮助吗
