Right now, the task of keeping track of what servers are in a cluster and what data they have is pushed off to the user. Zookeeper would keep track of that (and would also serve as a single point of configuration). Wouldn't it be nice to be able to start up another server like so: java -jar start.jar -Dcluster_id=foo And just have everything work (no updating loadbalancer configuration, other clients, etc). Then there is master failover - a somewhat harder problem... or very much harder, depending on how one approaches it. -Yonik http://www.lucidimagination.com
