             Summary: chown doesn't work with usernames containing '\' character
                 Key: HADOOP-14075
                 URL: https://issues.apache.org/jira/browse/HADOOP-14075
             Project: Hadoop Common
          Issue Type: Bug
            Reporter: Attila Bukor


Usernames containing backslash (e.g. down-level logon names) seem to work fine with Hadoop, except for chown.
