Matei Dragu commented on HADOOP-11999:
--------------------------------------
[~ehiggs] thank you for the quick reply but now I realised that I might have
misunderstood the bug contents.
I am experiencing the following problem:
If I set the yarn.nodemanager.webapp.address property one a node as HOST:PORT,
in the GUI of the ResourceManager that node registered with that setting is
ignored in the nodes list. Instead the yarn.nodemanager.webapp.address, the URL
displayed in the Node HTTP Address column is {yarn.manager.hostname}:PORT
Example:
If yarn.nodemanager.webapp.address is set to mywebhost:1234 and
yarn.manager.hostname is set to mynodehost, the node will appear as
mynodehost:1234 in the web GUI.
Is this a known behavior ?
YARN Version I am using: 2.6.0-cdh5.5.0
Thank you in advance!

> Issue Type: Bug
> Affects Versions: 2.3.0
> Environment: Linux.
> Reporter: Ewan Higgs
>
> I am setting up a Hadoop cluster where the nodes have FQDNames inside
> the cluster, but the DNS where these names are registered is behind some
> login nodes. So any user who tries to access the web interface needs to
> use the IPs instead.
> I set the 'yarn.nodemanager.webapp.address' and
> 'yarn.resourcemanager.webapp.address' to the appropriate IP:port. I
> don't give it the FQDN in this config field.
> However, when I access the web app it all works inside each web app.
> However, when I cross from the Resource Manager to the Node Manager web
> app, the href url uses the FQDN that I don't want. Obviously this is a
> dead link to the user and can only be fixed if they copy and paste the
> appropriate IP address for the node (not a pleasant user experience).
> I suppose it makes sense to use the FQDN for the link text in the web app,
> but not the actual url if the IP was specified.
