> dfsadmin reports 2x disk utilization on some platforms (Solaris, MacOS). The reason for this is that org.apache.hadoop.fs.DU is relying on du's default block size when reporting sizes and assuming they are 1024 byte blocks. This works fine on Linux, but du Solaris and MacOS uses 512-byte blocks to report disk usage.
> DU should use "du -sk" instead of "du -s" to force the command to report sizes based on 1024 byte blocks.
