> Project: ZooKeeper
> Issue Type: Bug
> Components: leaderElection
> Affects Versions: 3.5.7
> Reporter: Lasaro Camargos
> Assignee: Mate Szalay-Beko
> Priority: Major
> Attachments: node1.log, node2.log, node3.log

>
> In a cluster with three nodes, node3 is the leader and the other nodes are followers.
> If I stop node3, the other two nodes do not finish the leader election.
> This is happening with ZK 3.5.7, openjdk version "12.0.2" 2019-07-16, and this config
>

> Could you have a look at the logs and help me figure this out? It seems like node 1 is not getting notifications back from node2, but I don't see anything wrong with the network so I am wondering if bugs like ZOOKEEPER-3756 could be causing it.
