Subject [jira] Commented: (HADOOP-4546) Minor fix in dfs to make hadoop work in AIX
Date Wed, 25 Feb 2009 13:59:01 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-4546?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12676651#action_12676651
] 

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

The patch and supplied unit test work on AIX 6.1.  I have run the Hadoop unit tests against
my patched version also.  Prior to the patch about 60 tests fail, after the patch only 2 fail
for unrelated reasons (and I have created jira entries for those).   I noticed that the junit
test failed because disk space changed between calls.  What do you recommend be done to rework
the test so this patch will pass all requirements?

> 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.
