Subject [jira] Commented: (HADOOP-4546) Minor fix in dfs to make hadoop work in AIX
Date Mon, 02 Mar 2009 19:20:56 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-4546?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12678068#action_12678068

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

I see this still didn't get through Hudson again.  
For what it might be worth, I applied 4546-2.patch to 0.18.3 when I did all my unit testing
on AIX (I don't have a Java6 running on my AIX).  
I don't see any reason why this can't be included in 0.18.4 as the original code that is patched
has not been changed over the last few releases.

> 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.
