I updated the cassandra-env.sh
$JMX_HOST="10.20.30.40"
JVM_OPTS="$JVM_OPTS -Djava.rmi.server.hostname=$JMX_HOST"
netstat -ltn shows port 7199 is listening.
I tried both public and private IP for connecting but neither helps.
However, I am able to connect locally from within server.
I get this error when I remote:
Error connection to remote JMX agent! java.rmi.ConnectException:
Connection refused to host: 10.20.30.40; nested exception is:
