I can set this in standalone mode by using -Djboss.node.name=nodeA. I wonder, how can this be set for each node managed in domain mode?
I found that there is a small change in the node name when it is in domain mode compared to standalone mode. In standalone mode it is nodeA but in domain mode it is master:nodeA. Is there any way to make them the same?
What you're seeing in domain mode is the fully qualified name. It is telling you the host name, followed by the node name.
If you look in your host-master.xml, you will see the root tag looks like this:
<host name="master" xmlns="urn:jboss:domain:2.2">
If you change the host name to something like main, you will find that your fully qualified node name is main:nodeA.
You could remove the name attribute from the <host> (the host.xml file doesn't have it), but I wouldn't recommend it, because it can make things a bit more confusing in terms of management if you have a multiple hosts.
