Bill Habermaas updated HADOOP-4546:
-----------------------------------

    Attachment: hadoop-4546.patch
                TestDFVariations.java

The original patch author says he does not have an AIX system to finish this 
fix. I have made the suggested revision to the source, written a unit test, and 
tested the patch/unit test on AIX 6.1(in addition to running the normal ANT 
junit tests on that system). If I need to take further action to ensure this 
fix becomes permanently included in the system then please provide further 
guidance.

> 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.
