------------------------------------
Fix Version/s: trunk
Resolution: Fixed
> Inconsistent behaviour between root and non root sudo.py behaviour
> ------------------------------------------------------------------
>
> Key: AMBARI-26622
> URL: https://issues.apache.org/jira/browse/AMBARI-26622
> Project: Ambari
> Issue Type: Bug
> Affects Versions: trunk, 3.0.0, 3.1.0
> Reporter: Jeffrey Smith
> Priority: Major
> Fix For: trunk
>
> Time Spent: 20m
> Remaining Estimate: 0h

> In sudo.py, the makedir(path, mode) function has different behaviour
> depending on if Ambari is running as root or not.
> The root branch:
> {{def makedir(path, mode):}}
> os.mkdir(path)
> The non-root branch:
> {{def makedir(path, mode):}}
> {{ shell.checked_call(["mkdir", path], sudo=True)}}
> chmod(path, mode)
> This means that when Ambari is running as root, it is silently dropping the
> mode option but not doing so when run as any other user. This results in
> inconsistent behaviour between these two scenarios.
> According to the Python documentation, the default argument for mode is 0o777
> if not specified - this could create a situation where a folder is expected
> to be secure but is not actually since all users might be able to read/write
> to that directory.
> ({{{}from the docs: os.{}}}{{{}mkdir{}}}({_}path{_}, {_}mode=0o777{_},
> {_}*{_}, {_}dir_fd=None{_}))
> This is a simple fix - passing mode to {{os.mkdir(path, mode)}} when Ambari
> runs as root.
