Deploying Confluence DataCenter over an EC2 cluster

EC2 does not allow multicast, so I am unable to deploy Confluence DataCenter directly over two EC2 hosts.

I updated the Hazelcast jar to specify the hostnames statically, so that it can use TCP instead of multicasting. After starting up Confluence in both hosts, when I go back and refresh the page from the master node, it fails with a cache read error "HTTP Status 500 - Problem retrieving a value from cache com.atlassian.bandana.BandanaPersister" (Error shown below)

How can I fix this?

Is there anyone else here who has deployed Confluence DataCenter over an EC2 cluster? If so, could you share your experiences around deploying Confluence DataCenter over EC2?
