There are 3 ports that need to be opened 1) the client port (btw client and servers) 2/3) the quorum and election ports - only btw servers
You are setting these three ports in your config file (clientport defaults to 2181 iirc, unless you override)

Thanks for your help. The missing file issue is resolved. I was confused by how to start zookeeper because a firewall is blocking connections between nodes. The odd thing is hadoop can run on its own with the configured iptables but doesn't work with zookeeper for some reason. The problem here is I can't turn off the firewall and need to configure the firewall so that zookeeper can work correctly. I'm going to work on the iptables to open connections needed by zookeeper. If any one knows of a way to do this or even just a link to configuring an iptable with zookeeper in mind, I'd appreciate it. Thanks again for the help.

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
