Subject [jira] [Commented] (HADOOP-9914) nodes overview should use FQDNs
Date Thu, 29 Aug 2013 08:27:56 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-9914?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13753424#comment-13753424

André Kelpe commented on HADOOP-9914:

Sorry, I hit submit, but did not intend to. I found the issue, that /etc/hostname was not
exactly right. Funny enough, HDFS always worked fine. PEBKAC. Closing the issue.

>             Project: Hadoop Common
>          Issue Type: Bug
>    Affects Versions: 2.1.0-beta
>            Reporter: André Kelpe
> I am running a hadoop cluster in a bunch of VMs on my local machine and I am using avahi/zeroconf
to do local name resolution (this is to avoid having to fiddle with my /etc/hosts file). 
> The resourcemanager has an overview page, with links to all the nodemanager web-interfaces.
The links do not work with zeroconf, due to the fact that the links are not including the
domain part. zeroconf domains look like this "hadoop1.local", but the web-interface uses "hadoop1",
which will not resolve.
> In hadoop 1.x all web-interfaces were using FQDN, meaning using avahi/zeroconf for name
resolution was no problem. The same should be possible in hadoop 2.x.
> I am still beginning to work with hadoop 2.x, so there might be other parts, having the
same problem, but I am not yet aware of any. If I find more of these, I will update this bug.
