Subject [jira] Commented: (HIVE-78) Authentication infrastructure for Hive
Date Thu, 17 Sep 2009 17:57:58 GMT

    [ https://issues.apache.org/jira/browse/HIVE-78?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12756662#action_12756662

Namit Jain commented on HIVE-78:
--------------------------------

I think, we should spend some time on finalizing the functionality before implementing it
- it is very difficult to change something once it is out, due to all kinds of backward compatibility
issues.

For the syntax, AS

wont it be simpler to add permissions to a role, and then assign roles to a user.



GRANT WITH_GRANT,RC, ON '*' TO 'USER1','USER2' AS my_permission

ALTER GRANT my_permission add USER 'USER3'


Can I revoke some privileges from my_permissions ?

If yes, how is it different from doing the two things differently ?


CREATE ROLE my_permission AS GRANT WITH_GRANT,RC, ON '*' ;
GRANT my_permission to USER1, USER2;

later

GRANT my_permission to USER3;
