             Summary: Observers spam each other creating connections to the election addr
                 Key: ZOOKEEPER-1807
                 URL: https://issues.apache.org/jira/browse/ZOOKEEPER-1807
             Project: ZooKeeper
          Issue Type: Bug
            Reporter: Raul Gutierrez Segales
            Assignee: Raul Gutierrez Segales


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..).
