In OSX (and I guess also in Linux), this port is now located in /conf/cassandra-env.sh. You can change it by changing the JMX_PORT variable (line 165 in my case).

Check this question

8080 is used for remote JMX connection

Windows: cassandra.bat, -Dcom.sun.management.jmxremote.port=8080 (%JAVA_OPTS%)

Linux: cassandra.in.sh, -Dcom.sun.management.jmxremote.port=8080 ($JVM_OPTS)

You can just change the JMX port in cassandra-env.sh where it defines 'JMX_PORT="8080"' – Tyler Hobbs Dec 10 '10 at 21:01
