Subject [jira] Updated: (HADOOP-4546) Minor fix in dfs to make hadoop work in AIX
Date Mon, 02 Mar 2009 19:08:56 GMT

Chris Douglas updated HADOOP-4546:
----------------------------------

    Resolution: Fixed
        Status: Resolved  (was: Patch Available)

bq. I'm reopening this issue to resubmit patch to hudson.. For some reason hudson didnt accept
this patch..( possibly a jira issue)

The issue has been resolved and the patch committed to the repository. I'm assuming this was
accidental and part of a batch operation, but please accept my apologies if I misunderstand
your purpose. I'm re-marking this as "resolved".

bq. I see this is noted as fixed on 0.21 - any way it can be applied to 0.18.4? It needs to
be available for Java5 as well as Java6. AIX users are likely to need the Java5 version. Or
will the patch get applied to the Java5 version?

Unfortunately, it's not likely to be applied to any branch prior to 0.21 since this isn't
a regression. If this worked on AIX for some previous, released version of Hadoop, then one
could argue that the fix should be backported, but I don't think that's the case. Neither
am I certain we're going to roll an 0.18.4 release, anyway. Does AIX not have a Java6 port?

> 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.
