Nodetool command having issue when using it on remote host in the same cluster

if we run nodetool for any other host from a node in the same cluster, we are getting an error. Though it works fine for local host.

nodetool -h 10.241.17.81 status 
nodetool: Failed to connect to '10.241.17.81:7199' - ConnectException: 'Connection refused'.

Here, 10.241.17.81 is the remote host in the same cluster .

It doesn't work even after adding JVM_OPTS="$JVM_OPTS -Djava.rmi.server.hostname=10.241.17.81" in cassandra-env.sh and restarting the node.

Is there something related to broadcast_rpc_address?

rpc_address: 0.0.0.0
broadcast_rpc_address: 10.241.17.81
rpc_port: 9160
rpc_keepalive: true

You need to change the following in cassandra-env.sh:

if [ "x$LOCAL_JMX" = "x" ]; then
    LOCAL_JMX=yes

to

if [ "x$LOCAL_JMX" = "x" ]; then
    LOCAL_JMX=no

and

JVM_OPTS="$JVM_OPTS -Dcom.sun.management.jmxremote.authenticate=true"

to

JVM_OPTS="$JVM_OPTS -Dcom.sun.management.jmxremote.authenticate=false"

And restart the node.

Also, before making these changes, be sure to check your hosts by using the command:

netstat -antp.
