Hi, We know ZK demands odd number of servers to provide reliability. My requirement on having zookeeper in my application is to "know the application status" from all the clients(Max 100). And today my application can support deployment 1+1(=2) to N+1(=100) Given this I would like to go with 2 ZK servers in two different instances because adding one more server for this purpose would be demand one more instance itself in my 1+1 deployment model.
Questions: 1. What would happen to ensemble formed ? Would the service goes down automatically ? 2. What would be the impact if number ZK server instances are even (E.g. 2) How do I size a Zoo Keeper ensemble (cluster)? https://cwiki.apache.org/confluence/display/ZOOKEEPER/FAQ Designing a Zoo Keeper Deployment http://zookeeper.apache.org/doc/r3.1.2/zookeeperAdmin.html Thanks, Srini
