Subject [jira] [Commented] (YARN-3100) Make YARN authorization pluggable
Date Wed, 04 Feb 2015 21:56:35 GMT

    [ https://issues.apache.org/jira/browse/YARN-3100?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14306046#comment-14306046
] 

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

bq. The authorize.* package in common provides services some pretty generic ACL functionality.

As I said, YARN *is already re-using many code/library from this package*. If you found more
should be re-used, please let us know and feel free to file separate jira.
bq. Mentioning Ranger and/or Sentry should allow anyone to do anything they want. They are
magic words that make people run away.
This is anyways configurable by admin. People can choose to use or not to use. Nothing gets
affected for original implementation.

> 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.
