Just to clarify things: I'm trying to get my first cluster up and running and it's not working.
I have Cassandra working on one machine just fine, with all my data, but when I put Cassandra on a 2nd machine, and point it to my first machine, nothing happens. There seems to be some communication between the two machines, because when I stop Cassandra on the 1st machine, the 2nd machine tells me that the connection is lost.
