Subject [jira] [Commented] (YARN-3100) Make YARN authorization pluggable
Date Thu, 05 Feb 2015 06:36:35 GMT

    [ https://issues.apache.org/jira/browse/YARN-3100?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14306738#comment-14306738
] 

Chris Douglas commented on YARN-3100:
-------------------------------------

Motivation for the conversion from {{QueueACL}} to the nearly identical, new {{YarnAuthorizationProvider.AccessType}}-
like the introduction of {{PrivilegedEntity}}- is not obvious. Are these pluggable types?
Are there other, future entities besides queues? Should the authorizer plugin perform the
mapping from {{QueueACL}}? Just trying to understand the design...

For the {{Default\*}} impl, partial updates for {{refreshQueues}} that become visible during
the update and after a partial, failed update are hard to reason about. While it's a noop
for external services, aren't these different semantics from the current implementation? Readers
are blocked, so there are no locks necessary for modifications by {{setPermission}}?

> The goal is to have YARN acl model pluggable so as to integrate other authorization tool
such as Apache Ranger, Sentry.
> Currently, we have 
> - admin ACL
> - queue ACL
> - application ACL
> - time line domain ACL
> - service ACL
> The proposal is to create a YarnAuthorizationProvider interface. Current implementation
will be the default implementation. Ranger or Sentry plug-in can implement  this interface.
> Benefit:
> -  Unify the code base. With the default implementation, we can get rid of each specific
ACL manager such as AdminAclManager, ApplicationACLsManager, QueueAclsManager etc.
> - Enable Ranger, Sentry to do authorization for YARN.
