Chris Nauroth created HADOOP-9778:
-------------------------------------
Summary: Remove user name and group name validation logic from
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
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.
