Error connecting to remote JMX agent! while starting Nodetool

Question

I am trying to use nodetool against our Cassandra production database. But I am getting exception as soon as I try to start nodetool against Cassandra production cluster from my local machine.

S:\Apache Cassandra\apache-cassandra-1.2.3\bin>nodetool -h pdb.vip.phx.host.com compactionstats
Starting NodeTool

Can anyone provide some thoughts why I am seeing this exception? Any help will be appreciated.

Make sure that the JMX port listens on that interface – Schildmeijer May 12 '13 at 10:42 — Schildmeijer, May 12 '13 at 10:42

"Use JVM option '-Djava.rmi.server.hostname=$IP' (where $IP is the ip address of the interface you want to reach from the remote machine)."

Thanks for suggestion. In my local dev box from where I am trying to start the nodetool to see the stats of my production db cluster, I uncommented out the line that you mentioned above like this `JVM_OPTS="$JVM_OPTS -Djava.rmi.server.hostname=10.43.96.33"` and then I am trying to connect to that IP Address using nodetool, I am still getting the same exception. Is there anything else I am missing? – arsenal May 12 '13 at 19:33
