Subject [jira] Commented: (HADOOP-6634) AccessControlList uses full-principal names to verify acls causing queue-acls to fail
Date Fri, 19 Mar 2010 04:27:27 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-6634?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12847221#action_12847221

Vinod K V commented on HADOOP-6634:
-----------------------------------

bq. Hopefully ACLs will get updated to support both plain "user" and a principal name.
@Allen, I talked to Devaraj about this as he has deeper context. As he says, supporting is
not straightforward implementation-wise and needs more involved changes. The current issue
tracks a bug which completely causes queue-acls to fail. So I propose we only fix this bug
here and track the support for both plain user and long principal names in another JIRA issue.
Does that work?

> ACL configuration so far was using short user-names. With the changed {{UserGroupInformation}},
short names are different from the long fully-qualified names. {{AccessControlList}} continues
to use {{UserGroupInformation.getUserName()}} for verifying access control. Because of this,
queue acls fail for a user "user@domain.org" even though the short name "user" is part of
the acl configuration.
