----------------------------------------
> camel-zookeeper - a ZooKeeper cluster service stopped and started again never
> takes the leadership again

> Key: CAMEL-26801
> URL: https://issues.apache.org/jira/browse/CAMEL-26801
> Project: Camel
> Issue Type: Bug
> Components: camel-zookeeper
> Reporter: shashank
> Assignee: shashank
> Priority: Major
>
> {{ZooKeeperClusterView}} keeps the Curator client that
> {{ZooKeeperClusterService}} gave it when the view was created. When the
> service is stopped and started again (for example from JMX), it closes its
> managed Curator client and creates a new one, and starts its views again (the
> views in use are kept by the service). A view then creates its
> {{LeaderSelector}} on the closed client:
> * the node no longer takes part in the leader election: it never becomes the
> leader, also when all the other nodes go away;
> * the routes that use the view (clustered route policy, {{master}} component)
> never run on this node again. A restart of the CamelContext stops and starts
> the same service, which keeps its views, so it hits the same problem; only a
> restart of the application recovers.
> This is the ZooKeeper counterpart of CAMEL-25061 (file lock cluster service
> restart).
> Expected: a view started again after a restart of its service takes part in
> the election with the current client of the service.
> Suggested fix: the view gets the client from the service when it starts,
> instead of keeping the one it was created with.
> Found with Specula (TLA+ model checked against traces of the real code) and
> confirmed with a test on the real classes (ZooKeeper server in the test JVM).
> _Filed with Claude Code on behalf of allthingssecurity._
