Now that I have your attention..next question... :) Now I would like to start a Zookeeper Quorum on 3 EC Instances. Read the doc regarding... "Running Replicated ZooKeeper". It says "all servers in the quorum should have the same configuration file".. Does this mean... I should..
1) Download & Install ZooKeeper on all 3 instances (at the same location.) 2) Save the same zoo.cfg in /conf for all 3 instances. 3) On one instance (Master?), run... bin/zkServer.sh start Would that start ZooKeeper on all 3 instances?
