[jira] [Created] (HADOOP-9914) nodes overview should use FQDNs

André Kelpe created HADOOP-9914:
-----------------------------------

             Summary: nodes overview should use FQDNs
                 Key: HADOOP-9914
                 URL: https://issues.apache.org/jira/browse/HADOOP-9914
             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.
