I have small test cluster of 2 nodes. I ran a stress test on it and with
nodetool status received the following:
/usr/local/bin/apache-cassandra-2.0.0-rc1/log $ ../bin/nodetool status
Datacenter: datacenter1
=======================
Status=Up/Down
|/ State=Normal/Leaving/Joining/Moving
-- Address Load Tokens Owns (effective) Host ID
Rack
UN 192.168.0.11 141.13 MB 256 49.2%
4d281e2e-efd9-4abf-bb70-ebdf8e2b4fc3 rack1

I then added a third node with no machines writing to the system. Using
nodetool status I got the following:
/usr/local/bin/apache-cassandra-2.0.0-rc1/log $ ../bin/nodetool status
Datacenter: datacenter1

Is this correct ? I was under the impression that adding a node to an existing
cluster would distribute the load around the cluster. Am I perhaps missing a
step or have a config error perhaps ?
