> 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.
