[jira] [Commented] (TEZ-2277) modifyACLsStr in DAGAccessControls does not take effect

["Hitesh Shah (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/TEZ-2277?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14481586#comment-14481586 ] 

Hitesh Shah commented on TEZ-2277:
----------------------------------

Actually this is not a bug. The reason is that the write acls in Timeline are only needed for the user ( or set of users ) that are going to be updating the data in timeline. Although, the write acls are more powerful i.e. allow actions to be taken against the AM, there are not needed for timeline. For Tez, only the Tez AM running as the original user is writing to Timeline therefore no one else should really have permissions to update the data in Timeline.

> Even if modifyACLsStr in DAGAccessControls constructor is set and that access control is set for the DAG, it does not actually get set in access control at runtime.
