Sravya Tirukkovalur updated SENTRY-498:
---------------------------------------
Labels: roadmap (was: core roadmap)
> Sentry authorization V2 via Hive authorization framework
> --------------------------------------------------------
>
> Key: SENTRY-498
> URL: https://issues.apache.org/jira/browse/SENTRY-498
> Project: Sentry
> Issue Type: New Feature
> Reporter: Xiaomeng Huang

>
> Currently Sentry grant/revoke privileges via hook DDLTask, and do
> authorization via HiveSemanticAnalyzerHook. Now hive has a pluggable
> authorization framework via exposing some interfaces HiveAccessController and
> HiveAuthorizationValidator. HiveAccessController is used to grant/revoke
> roles and privileges. HiveAuthorizationValidator is used to do fine-grained
> authorization.
> Advantages to use this framework to grant/revoke privileges and do
> authorization:
> - This framework is very convenient to use by external authorization system.
> - Using this framework will be better accepted by community.
> - We don't need to take efforts to add so many hooks.
> - Some hooks has limitations. e.g. For column level security, we can't get
> accessed cloumns from query via HiveSemanticAnalyzerHook, so I extend the
> readEntity to put accessed columns into it(HIVE-7730). But if we use this
> framework, we don't need to extend the readEntity, we can just get accessed
> columns from ColumnAccessInfo directly.
> I will not remove the old sentry authorization framework, I will just add a
> new authorizationV2 via implement Hive authorization framework. If all the
> e2e tests passed, we can mark the old authorization deprecated.
