Question 1: JMX binding, Question 2: Logging
Hi all,
I'm fairly new to Cassandra. I'm deploying it to a PaaS. One thing this entails is that it must be able to have more than one instance on a single node. I'm running into the problem that JMX binds to 0.0.0.0:7199. My question is this: Is there a way to configure this? I have actually found the post that said to change the the following
JVM_OPTS="$JVM_OPTS -Djava.rmi.server.hostname=127.1.246.3" where 127.1.246.3 is the IP I want to bind to..
This actually did not change the JMX binding by any means for me. I saw a post about a "jmx listen address" in cassandra.yaml and this also did not work.
Any clarity on whether this is bindable at all? Or if there are plans for it?
Also-
I have logging turned on. For some reason, though, my Cassandra is not actually logging as intended. My log folder is actually empty after each (failed) run (due to the port being taken by my other cassandra process).
Here is an actual copy of my log4j-server.properites file: http://fpaste.org/74470/15510941/
Any idea why this might not be logging?
Thank you and best regards
Kyle

Hello Kyle,
For your first question, you need to create aliases to localhost e.g.
127.0.0.2,127.0.0.3 etc. this should get you going.
About the logging issue, I think if your instance failing before it gets to
long anything, as an example you can strart one instance and make sure it
logs correctly.
Hope that helps.

Unfortunately, you can't change the interface jmx binds to initially. So in
order to accomplish what you want you will need to use different jmx ports
for each process.
This is how ccm (https://github.com/pcmanus/ccm) accomplishes this as well.

Hi Andrey,
I only see a port for JMX. I do not see a value for the interface. I am using Cassandra 1.2.6
