Bill Habermaas commented on HADOOP-4546:
----------------------------------------

Chris: Patch 4546-2.patch has been applied and tested on AIX 6.1 and it works.  I assume that is what you are asking.  I have also run the test-core unit tests as well with the expected good results. 
Can we give this another shot?

> 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.
