Subject [jira] [Commented] (HADOOP-8455) Address user name format on domain joined Windows machines
Date Thu, 12 Jul 2012 07:31:35 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-8455?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13412582#comment-13412582

Owen O'Malley commented on HADOOP-8455:

This is already possible, by using the auth_to_local mapping. The cluster operator can define
arbitrary mappings between long (FOO@DOMAIN) and short names (DOMAINFOO).

> For a domain joined Windows machine, user name along is not a unique identifier. User
name plus domain name is need in order to unique identify the user. For example, we can have
both ‘Win1\Alex’ and ‘Redmond\Alex’ on a computer named Win1 that joins Redmond domain.
In order to avoid ambiguity, ‘whoami’ on Windows and the new ‘winutils’ created in
[Hadoop-8235|https://issues.apache.org/jira/browse/HADOOP-8235] both return [domain]\[username]
as the username. In Hadoop, we only use user name right now. This may lead to some inconsistency,
and production bugs if users of the same name exist on the machine.
