jboss cluster deploying issue - (while the service is up)

Hi Im kind of new to clustering. Please let me know if I can assign one node as Jboss coordinator where the other nodes always refer to that node for configuration.

My requirement
I have two nodes cluster (Lets say node A and B) and application is deployed under /farm. There are instances where i need to upgrade my EAR located in /farm with out service interruption. Therefore I shut down node A (while node B gives uninterrupted service to my clients) and upgrade EAR file inside /farm and startup. When the node A is up eventually i realized my old EAR has copied back to node A from node B. Therefore i had to restart both cluster nodes (with service interruption) in order to upgrade my application. I understand it takes the configuration from the node that exists for longest time. But as of for my requirement i need to configure whether to read it from other node or not. I heard if I can configure jboss coordinator it will be ok. But if any one knows how to do that or better solution for this please reply back.

If you can let me know a solution it would be greatly appreciated.
