Hi All, I'm having a problem with installing zookeeper on a cluster with 6 nodes in replicated mode. I was able to install and run zookeeper in standalone mode but I'm unable to run zookeeper in replicated mode.
I've added a list of servers in zoo.cfg as suggested by the ZooKeeper Getting Started Guide but I get these logs displayed to screen: *[r...@master1 bin]# ./zkServer.sh start JMX enabled by default Using config: /root/zookeeper-3.2.2/bin/../conf/zoo.cfg Starting zookeeper ...

Am I supposed to have an instance of ZooKeeper on each node started before running in replication mode? Should I have each node that will be running ZK listed in the config file? Should I be using an IP address to point to a server instead of a hostname? Thanks for your time. Erik
