> Hey [~shralex],
> I noticed today that my Observers are spamming each other trying to open
> connections to the election port. I've got tons of these:
> {noformat}
> 2013-11-01 22:19:45,819 - DEBUG [WorkerSender[myid=13]] - There is a
> connection already for server 9
> 2013-11-01 22:19:45,819 - DEBUG [WorkerSender[myid=13]] - There is a
> connection already for server 10
> 2013-11-01 22:19:45,819 - DEBUG [WorkerSender[myid=13]] - There is a
> connection already for server 6
> 2013-11-01 22:19:45,819 - DEBUG [WorkerSender[myid=13]] - There is a
> connection already for server 12
> 2013-11-01 22:19:45,819 - DEBUG [WorkerSender[myid=13]] - There is a
> connection already for server 14
> {noformat}
> and so and so on ad nauseam.
> Now, looking around I found this inside FastLeaderElection.java from when you
> committed ZOOKEEPER-107:
> {noformat}
> private void sendNotifications() {
> - for (QuorumServer server : self.getVotingView().values()) {
> - long sid = server.id;
> -
> + for (long sid : self.getAllKnownServerIds()) {
> + QuorumVerifier qv = self.getQuorumVerifier();
> {noformat}
> Is that really desired? I suspect that is what's causing Observers to try to
> connect to each other (as opposed as just connecting to participants). I'll
> give it a try now and let you know. (Also, we use observer ids that are > 0,
> and I saw some parts of the code that might not deal with that assumption -
> so it could be that too..).
