Curious if anyone could shed some light on this. Trying to set up a 4-node, one DC (for now, same region, same AZ, same VPC, etc) cluster in AWS.
All nodes have the following config (everything else basically standard): cassandra.yaml: listen_address: NODE?_PRIVATE_IP seeds: "NODE1_ELASTIC_IP" endpoint_snitch: Ec2MultiRegionSnitch cassandra-rackdc.properties: empty except prefer_local=true I've tried setting broadcast_address: NODE?_ELASTIC_IP But that didn't help - and it seems redundant, as it appears that that's what the Ec2MultiRegionSnitch does anyway. Node 1 starts up fine, because it's the seed. No other nodes will start, reporting: "Exception (java.lang.RuntimeException) encountered during startup: Unable to gossip with any seeds" Adding iptables rules to the nodes to translate outgoing packets with destination of NODE?_ELASTIC_IP to destination of NODE?_PRIVATE_IP solves the issue, but that seems like a hack. (For Example: iptables -t nat -A OUTPUT -p tcp -d ELASTIC_IP -j DNAT --to-destination PRIVATE_IP) Not sure if I'm missing a config item, or something in AWS is blocking me, or if 3.11.2 has an issue. Thanks, Voytek Jarnot
