> Key: HADOOP-2983
> URL: https://issues.apache.org/jira/browse/HADOOP-2983
> Project: Hadoop Core
> Issue Type: Bug
> Components: contrib/hod
> Affects Versions: 0.16.0
> Environment: Linux, PBS
> Reporter: Craig Macdonald
> Attachments: HOD_util_local_fqdn.py,
> HOD_util_local_fqdn_AL_GRANTED.patch
>
>
> For some reason (probably in our local DNS setup) gethostbyname_ex() does not
> return any fully qualified hostnames. This has never been an issue,
> everything has worked fully with the hostnames.
> However, this causes HOD to fail, as local_fqn() in util.py returns None.
> {noformat}
> Python 2.5.1 (r251:54863, Sep 21 2007, 16:05:06)
> [GCC 3.4.6 20060404 (Red Hat 3.4.6-3)] on linux2
> Type "help", "copyright", "credits" or "license" for more information.
> >>> import socket, os
> >>> socket.gethostbyname_ex(os.uname()[1])
> ('bohol', [], ['130.209.252.70'])
> >>>
> {noformat}
> The solution is to fix local_fqdn in until.py, such that it falls back to the
> contents of the variable me if fqdn is still None.
> Ta muchly.
