Major Description
Running in 3.4 compatibility mode, Curator improperly appears to attempt to call the close(I) method which does not exist on the 3.4 version of the Zookeeper API:
Uncaught error from thread [timeline-manager-akka.actor.default-dispatcher-4]: org.apache.zookeeper.ZooKeeper.close(I)Z, shutting down JVM since 'akka.jvm-exit-on-fatal-error' is enabled for ActorSystem[timeline-manager] java.lang.NoSuchMethodError: org.apache.zookeeper.ZooKeeper.close(I)Z at org.apache.curator.HandleHolder.internalClose(HandleHolder.java:164) at org.apache.curator.HandleHolder.closeAndClear(HandleHolder.java:78) at org.apache.curator.ConnectionState.close(ConnectionState.java:125) at org.apache.curator.CuratorZookeeperClient.close(CuratorZookeeperClient.java:266) at org.apache.curator.CuratorZookeeperClient.close(CuratorZookeeperClient.java:249)
This results in a failure to reconnect to Zookeeper when the service is restarted (presumably because the old connection was never properly released).
