> Reporter: Ivan A. Veselovsky

> test org.apache.hadoop.fs.TestLocalFileSystem.testReportChecksumFailure() (added in HADOOP-9067) appears to fail on MacOS because
> method org.apache.hadoop.fs.DF.getMount() does not work correctly.
> The problem is that "df -k <path>" command returns on MacOS output like the following:
> -------
> Filesystem 1024-blocks Used Available Capacity iused ifree %iused Mounted on
> /dev/disk0s4 194879828 100327120 94552708 52% 25081778 23638177 51% /Volumes/Data
> -------
> while the following is expected:
> -------
> Filesystem 1024-blocks Used Available Capacity Mounted on
> /dev/mapper/vg_iveselovskyws-lv_home 420545160 15978372 383204308 5% /home
> -------
> So, we see that Mac's output has 3 additional tokens.
> I can suggest 2 ways to fix the problem.
> (a) use "-P" (POSIX) option when invoking df command. This will probably ensure unifirm output on all Unix systems;
> (b) move Mac branch to specific "case" branch and treat it specifically (like we currently have for AIX, DF.java, line 214)
