Subject [jira] Commented: (HADOOP-6510) doAs for proxy user
Date Sat, 30 Jan 2010 21:07:34 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-6510?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12806740#action_12806740
] 

Owen O'Malley commented on HADOOP-6510:
---------------------------------------

After off line discussion, I'd propose changing TokenIdentifier from:

{noformat}
public abstract Text getUsername();
{noformat}

to 

{noformat}
public abstract UserGroupInformation getUser();
{noformat}

Tokens that don't have users can return null, while if it is a delegation token it can faithfully
create the correct UGI.

I'll also change my mind about mixing groups and users in the target list and say we should
only allow group names.
