I use version 0.7.4, I've done something like this: 1. I ssh to my Eucalyptus account and applied 1 instance, got a public IP and a internal IP. 2. I scp the tar ball of apache-cassandra-0.7.4-bin.tar.gz to root of my instance, unzip it and create directories 3. I run /bin/cassandra -f, everything is fine. 4 I run cassandra-cli in another terminal (on the same instance), link to localhost, everything is fine. 5 I run nodetools -h <MY PUBLIC IP> ring, when I hit enter, the machine became idle, there is no feedback. 6 So I run nodetools -h <MY INTERNAL IP> ring, I got a very long error:
