First make sure you really need clustering. Unless all hosts are in the
same zone federation might be a better option. See
for a discussion.

If you control DNS and all hosts are in the same domain then configuring
a default search domain should be sufficient. That will have a similar
effect to placing entries  in the /etc/hosts files for each node.

If the conditions for that solution are not met then you could manually
change all the instances of "-sname" to "-name" in the broker startup
scripts. Unfortunately the default release of rabbitmq-server does not
offer this as a configuration option and this configuration has not
received much testing. If you do select this option then we would
appreciate your feedback.
