> zk server: 3.7.2
> After [https://github.com/apache/curator/pull/430], after the zk was down and
> recovered, the LeaderLatch called getChildren() instead of reset() to recover
> the leader election. But getChildren() triggers setNode() via callback
> client.getChildren().inBackground(callback).forPath(ZKPaths.makePath(latchPath,
> null)). If the leaderPath node doesn't exist after zk recovered, then the
> LeaderLatch node wouldn't never recreated.
> There is a temporary solution, adding a ConnectionStateListener before the
> LeaderLatch internal ConnectionStateListener, to create the leaderPath node
> manually. Then this issue will be fixed.
