                 Key: HADOOP-3098
                 URL: https://issues.apache.org/jira/browse/HADOOP-3098
             Project: Hadoop Core
          Issue Type: Bug
          Components: fs
    Affects Versions: 0.16.1, 0.16.0
            Reporter: Koji Noguchi
            Priority: Blocker
             Fix For: 0.16.2


:~$ hadoop dfs -chown aaa_bbb  /user/knoguchi/test.txt
chown: 'aaa_bbb' does not match expected pattern for [owner][:group].

in 0.16.1, only alphabets and numbers are allowed.  Shouldn't '_' be allowed?

I couldn't find any standard, but in Solaris10, it's defined as 

http://docs.sun.com/app/docs/doc/816-5174/6mbb98uhg?a=view

bq. The login (login) and role (role) fields accept a string of no more than 
eight bytes consisting of characters from the set of alphabetic characters, 
numeric characters, period (.), underscore (_), and hyphen (-). The first 
character should be alphabetic and the field should contain at least one lower 
case alphabetic character. A warning message is displayed if these restrictions 
are not met.
