------------------------------------------
Hi Arun, your patch looks good. Would it be possible for you to write a unit
test as Steve suggested? The details are explained in
http://wiki.apache.org/hadoop/HowToContribute
A minor comment about the patch: it would be nice if you can create a enum
named DF.OSType that follows the pattern in
src.core.org.apache.fs.FileUtil.HardLink.OSType. Then it will be elegant to add
newer platform support for DF parsing in the future.

> HDFS uses df command to get the disk space. The output format of df command
> is different in AIX compared to Linux and Solaris. Checking the OS type and
> then reading the df output as per the format will fix this issue and thus
> allows hadoop to be fully functional in AIX environment.
