Subject [jira] [Commented] (CASSANDRA-2491) A new config parameter, broadcast_address
Date Fri, 17 Jun 2011 22:22:47 GMT


Brandon Williams commented on CASSANDRA-2491:

It goes away when the patch is removed and is 100% reproducible with the patch.  All nodes
are running the same version (but that shouldn't be a problem anyway.)

> A new config parameter, broadcast_address
> In a cluster setup where one or more nodes is behind a firewall and has a private ip
address, listen_address does not allow the hosts behind the firewalls to be discovered by
other nodes.
> Attached is a patch that introduces a new config parameter broadcast_address which allows
Cassandra nodes to explicitly specify their external ip address. 
> In addition, this allows listen_address to be set to on the already firewalled
> broadcast_address fallsback to listen_address when it is not stated.
