----------------------------------------

I am not sure how a patch should be created. I assume it would be a diff 
output. I have attached the diff output of the changes I have made to make it 
work on AIX. Hope this helps.

> 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.
