Default Listen Port
What's the easiest way to change the port nodes listen for comm on from other nodes? It appears that the default is 8080 which collides with my tomcat server on one of our dev boxes. I tried doing something in cassandra.yaml like
listen_address: 192.1.fake.2:7777
but that doesn't work it throws an exception. Also can you not put the actual name of servers in the config or does it always have to be the actual ip address currently? Thanks.

8080 is used by jmx [1]. You can change that in cassandra-env.sh.
hostnames are allowed.

You are having a collision on 8080 which is the default JMX port.
In conf/cassandra-env.sh
look for JMX_PORT="8080"
9160 is the thrift port used by clients
7000 is the storage port (used between nodes)
If you change the jmx port you have specify it when using nodetool,
'nodetool -h localhost -p <new port> ring'
