- 如果数据库下的表由多个用户创建，那么执行Drop database命令会失败，即使执行的用户是数据库的拥有者。
- 在二级索引中，当父表（parent table）触发时，insert和compaction将在索引表上触发。 如果选择具有过滤条件匹配索引表列的查询，用户应该为父表和索引表提供选择权限。
- LockFiles文件夹和LockFiles文件夹中创建的锁定文件将具有完全权限，因为LockFiles文件夹不包含任何敏感数据。
- 如果使用ACL，确保不要为DDL或DML配置任何被其他进程使用中的路径，建议创建新路径。
1) carbon.badRecords.location
2) 创建数据库时Db_Path及其他。
- 对于非安全集群中的Carbon ACL权限，hive-site.xml中的参数hive.server2.enable.doAs必须设置为false。 将此属性设置为false，查询将以hiveserver2进程运行的用户身份运行。
