TestHardLink fails on Mac OS X, when gnu stat is in path
--------------------------------------------------------

                 Key: HADOOP-7680
                 URL: https://issues.apache.org/jira/browse/HADOOP-7680
             Project: Hadoop Common
          Issue Type: Bug
    Affects Versions: 0.22.0, 0.23.0, 0.24.0
         Environment: Mac OS X, where `which stat` = /opt/local/libexec/gnubin/stat
            Reporter: Milind Bhandarkar
            Assignee: Milind Bhandarkar
             Fix For: 0.22.0, 0.23.0, 0.24.0


For a specific reason, `which stat` = /opt/local/libexec/gnubin/stat, on my Mac. o.a.h.f.HardLink
checks for os.name, detects it's a MacOSX, and assumes that stat points to /usr/bin/stat,
and uses -f%l as arguments, which fails. The upcoming patch explicitly sets stat to use /usr/bin/stat
on Mac OS. In 0.22, this code is part of o.a.h.f.FileUtil, and in 0.23 and trunk it is in
o.a.h.f.HardLink. Both patches forthcoming.
