Requiring super user for getStats

https://issues.apache.org/jira/browse/HADOOP-2659 introduced needing super
user to call getStats and was wondered why it was added since the POSIX stat
method doesn't require super. this prevents us from correctly implementing
the POSIX stat function:  https://issues.apache.org/jira/browse/HADOOP-4368.


>From man stat:

       You do not need any access rights to the file to
       get this information but you need search rights to all directories
named in the path leading to the file.

Thanks, pete

Hey Pete,

Actually, isn't this issue for the statfs call, not stat?

getStats returns the used/free/total space for the whole system.
