Daryn Sharp commented on HADOOP-9778: ------------------------------------- If we are *nix shell expanding usernames, that definitely needs to be fixed. I personally agree with the original premise of let the OS decide but I suppose you could make the pattern ".*" if that's what you want. > Support configurable user name and group name validation patterns in chown > and chgrp shell commands. > ---------------------------------------------------------------------------------------------------- > > Key: HADOOP-9778 > URL: https://issues.apache.org/jira/browse/HADOOP-9778 > Project: Hadoop Common > Issue Type: Improvement > Components: fs > Affects Versions: 3.0.0, 2.3.0 > Reporter: Chris Nauroth > Priority: Minor > > The chown and chgrp shell commands enforce a valid set of characters for user > names and group names. The validation rules for user names and group names > vary across different OSes, so this is a portability problem and a > maintenance burden. It requires us to change the code every time we discover > a difference in the rules. I propose that we remove this validation logic > and instead pass through input user names and group names to the OS. We can > handle error reporting by catching errors returned from the OS. -- This message is automatically generated by JIRA.
