-------------------------------------
Summary: Add ability to specify a negative 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
Reporter: Benoy Antony
Assignee: Benoy Antony
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 negative acs for services, then
administrator can disable users by specifying the users in negative acls. 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.
