Subject [jira] [Commented] (SENTRY-1004) Create CommonPrivilege for external component
Date Tue, 09 Feb 2016 13:24:18 GMT

    [ https://issues.apache.org/jira/browse/SENTRY-1004?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15138932#comment-15138932
] 

Colin Ma commented on SENTRY-1004:
----------------------------------

Yes, [~coheigea], the CommonPrivilege should replace all of the Privileges finally. Another
subtask(SENTRY-1042) is for the CommonPolicy.
Here is my plan: after SETNRY-1004 and SENTRY-1042, all current implementation for external
components will be replaced by CommonPrivilege and CommonPolicy.

> Create CommonPrivilege for every component.
> The main change is for the interface Privilege, implies(Privilege p)  --->  implies(Privilege
privilege, Map<String, String> implyMethodMap, Map<String, Integer> actionMap)
> The actionMap is stored the mapping between action name and action value, eg:
>      for Hive:   select   --->   1   (binary: 0000001)
>                       insert  --->    3   (binary: 0000011)
>                      create --->     4   (binary: 0000100)
>                         all    --->     7   (binary: 0000111)
> when compare the action, use the action value with the & operator
>  The implyMethodMap is stored the mapping between resource type and imply method, eg:
>      for Hive:    db   --->   string  (imply as string value)
>                       url  --->   url     (imply as url value)
