Hi, I replacing one of the zookeeper server from 3 node quorum. Initially all zookeeper serves were running 3.5.0.1515976 version. I successfully replaced Node3 with newer version 3.5.0.1551730. When I am trying to replace Node2 with the same zookeeper version. I couldn't start zookeeper server on Node2 as it is continuously stuck in leader election loop printing following messages:
2014-02-26 02:45:23,709 [myid:3] - INFO [QuorumPeer[myid=3]/0:0:0:0:0:0:0:0:2181:FastLeaderElection@837] - Notification time out: 60000 2014-02-26 02:45:23,710 [myid:3] - INFO [WorkerSender[myid=3]:QuorumCnxManager@195] - Have smaller server identifier, so dropping the connection: (5, 3) 2014-02-26 02:45:23,712 [myid:3] - INFO [WorkerReceiver[myid=3]:FastLeaderElection@605] - Notification: 3 (n.leader), 0x0 (n.zxid), 0x1 (n.round), LOOKING (n.state), 3 (n.sid), 0x0 (n.peerEPoch), LOOKING (my state)1 (n.config version) Network connections and configuration of the node being upgraded are fine. The other 2 nodes in the quorum are fine and serving the request. Any idea what might be causing this? Thanks & Regards, Deepak
