Thank Michael. Adding the config to the file I can configure the port and address to use with mx4j.
Wei Zhu, you are right. If you only add the mx4j-tool to the classpath cassandra enable mx4j by default using the default port 8081. 2012/11/12 Wei Zhu <wz1...@yahoo.com> > In my cassandra-env.sh for 1.1.6, there is no setting regarding mx4j at > all.
