Description

I have local JMX enabled but it isn't listening on localhost. This is how Cassandra is running

Note these:

-Dcassandra.jmx.local.port=7199 -Dcom.sun.management.jmxremote.authenticate=false -Djava.rmi.server.hostname=127.0.0.1

But I am still seeing this:

tcp        0      0 0.0.0.0:7199            0.0.0.0:*               LISTEN      12008/java          

No matter how I configure it I cannot get it to not listen on 0.0.0.0 and instead listen on 127.0.0.1, even following the configuration notes in cassandra-env.sh.
