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

I see. got your point. I'll fix this in next patch. thanks !
And I think the existing code will have this problem when exception thrown 
[here| 
https://git1-us-west.apache.org/repos/asf?p=hadoop.git;a=blob;f=hadoop-yarn-project/hadoop-yarn/hadoop-yarn-server/hadoop-yarn-server-resourcemanager/src/main/java/org/apache/hadoop/yarn/server/resourcemanager/scheduler/capacity/LeafQueue.java;h=c1432101510b30cab5979223c4a52b813cfc7aee;hb=HEAD#l497].
 I can open a jira for this, if you also think this is an issue.

> Make YARN authorization pluggable

>             Project: Hadoop YARN

>            Reporter: Jian He

> 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.
