node tool passes the host name un modified to the JMX library to connect to the
host.
The JMX server will, by default, bind to the ip address of the machine.
If the host name was wrong, I would guess the JMX service failed to bind.

I'm afraid that did not work. I'm running JMX on port 7199 (the
default) and I verified that the port is open and accepting
connections.
Here's what I'm seeing:
dmuth@devteam:~/cliq (production) $ nodetool --host localhost --port 7199 ring
Error connection to remote JMX agent!

To recap, my machine originally had the IP address of 10.244.207.16.
Then I shutdown/restarted that EC2 instance, and it had

Hi folks,
I'm a relative newbie to Cassandra, and have been trying to get up to
speed on it so that I can start using it at $WORK.
I ran into an interesting issue the other day with nodetool. I
currently have Cassandra running on an Amazon EC2 instance running
Ubuntu 10.10. At one point, I
specify the jmx port to nodetool, hard coded in conf/cassandra-env.sh
nodetool -h localhost -p [jmx port] ring
