Subject Re: dfs.permissions.superusergroup not working

Is there a typo in your email, or did you set dfs.cluster.administrators
instead of intending to set dfs.permissions.superusergroup?

Also, are your id outputs from the NameNode machines? Cause by default the
group lookups happen local to your NameNode machine.
