If the client-side ZooKeeper libraries can reestablish the communication channel to ZooKeeper, DataMonitor simply kicks everything off again with the call to ZooKeeper.exists(). If it gets an event for a znode, it calls ZooKeeper.exists() to find out what has changed. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
