JMX and nodes on firewall
« on: May 23, 2013, 09:35:50 PM »


I have a setup where the nodes are connecting to the server through a firewall. I can submit/receive job results but somehow JMX doesn't work on the nodes. The firewall is only work in one direction (nodes -> server). Which means the server can connect to any ports on the nodes. I already opened ports 11111 and 11198 on the server to the nodes. So, the question is what should I do to enable JMX on the nodes?

Thanks a lot

Each node also has its own JMX server, so you would need to open the port it listens to on the node's machine. In the current node distribution, this is port is 12001. More generally it is the value of the node configuration property "", which you can find in the node's configuration file.

I hope this helps,

Thanks for the fast reply.

But do I need to open port 12001 on the node or the server? Our firewall only filter traffic from nodes to server so the server can access port 12001 of the nodes.
