Using VMWare Pro Work Station, I have two Ubuntu VMs (clones of each other except MACs different). Simple basically default setup. I have installed Java and Apache Cassandra on each VM. One is configured for 127.0.0.3, the other 127.0.0.4. Individually both instances come up fine on their assigned IPs. However, when I change the settings in the config to allow them them to 'find' each other, so that the two can bind as a cluster, the connection from each to the other is refused. Here is an example message:
127.0.0.3:7000->/127.0.0.4:7000-URGENT_MESSAGES-[no-channel] failed to connect io.netty.channel.AbstractChannel$AnnotatedConnectException: finishConnect(..) failed: Connection refused: /127.0.0.2:7000Caused by: java.net.ConnectException: finishConnect(..) failed: Connection refused, etc.
BTW - firewall on VMs are inactive. And each IP does ping to the other.
Any suggestions are appreciated.
