I'm doing exactly that Marcos as follows from what I said originally:
"To set JMX's port I am using the following to run the server:
env JMX_PORT=10000 && bin/kafka-server-start.sh config/server2.properties"
To clarify, this is how I start the second server. The first server is
started with JMX port 9999.
