> Key: ZOOKEEPER-2791
> URL: https://issues.apache.org/jira/browse/ZOOKEEPER-2791
> Project: ZooKeeper
> Issue Type: Bug
> Components: leaderElection, quorum
> Affects Versions: 3.3.6, 3.4.8
> Environment: Ubuntu 14.04.4 LTS, AWS EC2, 5 node ensembles
> Reporter: Mike Heffner
> Assignee: Abraham Fine
>
> When zxid rolls over the ensemble is unable to recover without manually
> restarting the cluster. The leader enters shutdown() state when zxid rolls
> over, but the remaining four nodes in the ensemble are not able to re-elect a
> new leader. This state has persisted for at least 15 minutes before an
> operator manually restarted the cluster and the ensemble recovered.
