I have a 5 server ZK cluster. I want to connect to it using the CLI from
some remote machine. Is there any particular set up that I need to connect?
I am running it as zkCli.sh -server <server name> where the server name is
one of the servers in the ZK cluster. Is this correct? I can get a string of
Connect Exceptions as shown below:
