> When trying to get Hadoop up and running on Solaris on a ZFS filesystem, I encountered a problem where the capacity reported was zero:
> Configured Capacity: 0 (0 KB)
> It looks like the problem is with the 'df' output:
> $ df -k /data/hadoop 
> Filesystem           1024-blocks        Used   Available Capacity  Mounted on
> /                              0     7186354    20490274    26%    /
> The following patch (applied to trunk) fixes the problem.  Though the real problem is with 'df', I suspect the patch is harmless enough to include?
