Amos Feng commented on WFLY-1119:
---------------------------------
{code}
public static final SimpleAttributeDefinition NODE_IDENTIFIER = new
SimpleAttributeDefinitionBuilder(CommonAttributes.NODE_IDENTIFIER, ModelType.STRING,
true)
.setDefaultValue(new ModelNode().set("1"))
.setFlags(AttributeAccess.Flag.RESTART_ALL_SERVICES)
.setAllowExpression(true)
.setValidator(new StringBytesLengthValidator(0,23,true,true))
.build();
{code}
So it should remove the default value and if the node-identifier is undefined we need to
generate a true uuid and persist in the standalone.xml
It looks like the max length for node-name is 24 ?
I will take a look at the way to check attributes of other servers.
Assign an unique NodeID automatically

Priority: Optional
It shouldn't be needed to assign the node-id manually IMO.
You could store the node-id on a file and recover it for subsequent starts.
On hornetQ for instance, we look for the nodeID on a file, if the file doesn't exist
we assign a UUID and write to the file.
In our previous experience UUID would be a best fit to assign the nodes since that was
the only way we could guarantee unique IDs between the nodes.
