I am trying to spin up a new node using cassandra 2.0.7. Both nodes are at Digital Ocean. The seed node is up and running and I can telnet to port 7000 on that host from the
Ok, after spending a whole day at this, I eventually found the #cassandra IRC channel on freenode. (that's my first advice, go there, regularly)
The issue that you're experiencing is most likely (and was, in my case) what's called a 'chicken and the egg' problem. Chicken and the egg: Node 1: seeds=node2 Node 2: seeds=node1
Neither node can boot properly, because there's no seed node that's fully booted at.. boot time.
To solve this, just set: Node 1: seeds = node1,node2 Node 2: seeds = node2.
Now, node1 will boot. Node 2 will eventually boot as well..
Voila.
