Arpit Agarwal commented on HADOOP-10650: ---------------------------------------- Could you please add a comment to {{protocolToAcls}} stating that the the first ACL in the array is allow and the second one is deny. +1 with this change, the patch looks good otherwise. > Add ability to specify a reverse ACL (black list) of users and groups > --------------------------------------------------------------------- > > Key: HADOOP-10650 > URL: https://issues.apache.org/jira/browse/HADOOP-10650 > Project: Hadoop Common > Issue Type: Sub-task > Components: security > Reporter: Benoy Antony > Assignee: Benoy Antony > Attachments: HADOOP-10650.patch, HADOOP-10650.patch > > > Currently , it is possible to define a ACL (user and groups) for a service. > To temporarily remove authorization for a set of users, administrator needs > to remove the users from the specific group and this may be a lengthy process > ( update ldap groups, flush caches on machines). > If there is a facility to define a reverse ACL for services, then > administrator can disable users by specifying the users in reverse ACL. In > other words, one can specify a whitelist of users and groups as well as a > blacklist of users and groups. > One can also specify a default blacklist to disable the users from accessing > any service. -- This message was sent by Atlassian JIRA (v6.2#6252)
