>             Project: Hadoop Common
>          Issue Type: Bug
>          Components: fs
>    Affects Versions: 2.0.5-alpha
>            Reporter: Marc Villacorta
>            Assignee: Andras Bokor
>            Priority: Minor
>         Attachments: HADOOP-9851.01.patch

>
> I intend to set user and group:
> *User:* _MYCOMPANY+marc.villacorta_
> *Group:* hadoop
> where _'+'_ is what we use as a winbind separator.
> And this is what I get:
> {code:none}
> sudo -u hdfs hadoop fs -touchz /tmp/test.txt
> sudo -u hdfs hadoop fs -chown MYCOMPANY+marc.villacorta:hadoop /tmp/test.txt
> -chown: 'MYCOMPANY+marc.villacorta:hadoop' does not match expected pattern for [owner][:group].
> Usage: hadoop fs [generic options] -chown [-R] [OWNER][:[GROUP]] PATH...
> {code}
> I am using version: 2.0.0-cdh4.3.0

> winbind separator
>        The winbind separator option allows you to specify how NT domain names
>        and user names are combined into unix user names when presented to
>        users. By default, winbindd will use the traditional '\' separator so
>        that the unix user names look like DOMAIN\username. In some cases this
>        separator character may cause problems as the '\' character has
>        special meaning in unix shells. In that case you can use the winbind
>        separator option to specify an alternative separator character. Good
>        alternatives may be '/' (although that conflicts with the unix
>        directory separator) or a '+ 'character. The '+' character appears to
>        be the best choice for 100% compatibility with existing unix
>        utilities, but may be an aesthetically bad choice depending on your
>        taste.
>        Default: winbind separator = \
>        Example: winbind separator = +
> {quote}
