Hi Kevin, I had the response set up but didn't hit send. Ted already answered your question, but to give you a more technical background assuming that you know a little bit more about transaction ids in ZooKeeper and server ids:
If B and C are partitioned from each other, and A is the leader, there would not be a problem since A can talk to B and C and the cluster would continue functioning. But if B/C is the Leader then the other would get disconnected and stop functioning unless the partition heals. The clients connected to this server will get disconnected with connected to the working quorum of A and B/C. If a quorum election happens in this situation, there are two possibilities 1) A is the leader 2) A is not the leader If A is not Leader either B or C is the leader and the quorum functions with the disconnected server not functioning. If A is the leader then since it can talk to both B and C, all three servers will function and will work all fine. Hope that answers your question. Thanks mahadev In the first case A will not be the lea On 4/29/10 11:22 AM, "Kevin Webb" <kcw...@cs.ucsd.edu> wrote: > Suppose I have three zookeeper servers (A, B, and C).
