All I have to say is wow! I never tried jconsole before. I have
hadoop_trunk checked out and the JMX has all kinds of great
information. I am going to look at how I can get JMX/cacti/and hadoop
working together.

Just as an FYI there are separate ENV variables for each now. If you
override hadoop_ops you get a port conflict. It should be like this.

export HADOOP_NAMENODE_OPTS="-Dcom.sun.management.jmxremote.authenticate=false

Thanks Brian.
