Hi Bill,

Could you take a look at the "read-only" server mode. 

Following are some of the development thoughts from wiki. I hope this will give 
some more information.

Probably you can try connecting the zookeeper shell using -r option, this is 
for 'can be read only' client.

bin/zkCli.sh -server machineIP:clientPort -r
