Subject [jira] [Commented] (YARN-3100) Make YARN authorization pluggable
Date Fri, 06 Feb 2015 19:51:37 GMT

    [ https://issues.apache.org/jira/browse/YARN-3100?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14309757#comment-14309757
] 

Jian He commented on YARN-3100:
-------------------------------

bq. AbstractCSQueue and CSQueueUtils
Maybe I missed something, I think these two are mostly fine. As we create the new queue hierarchy
 first and then update the old queues. If certain methods fail in these two classes,  the
new queue creation will fail upfront and  so will not update the old queue. Anyway, we can
address this separately.

> 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.
