CarbonData访问控制

下表提供了对CarbonData Table执行相应操作所需的Hive ACL特权的详细信息。

前提条件

已经设置了表5表6中Carbon相关参数。

  • 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。

    以下配置项需要配置路径:

    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。
