Hi raghu, http://wiki.apache.org/hadoop/ZooKeeper/FAQ Explains on what timeouts mean for a zookeeper client. A timeout does not mean a closed session. The client will reconnect to another server and then renew the session. A closed session will make the zoookeeper handle invalid.
Hope this helps. Their is more info at http://wiki.apache.org/hadoop/ZooKeeper/Troubleshooting And also http://hadoop.apache.org/zookeeper/docs/r3.1.1/zookeeperProgrammers.html#ch_ zkSessions mahadev On 4/21/09 12:00 AM, "rag...@yahoo.com" <rag...@yahoo.com> wrote: > > I have a question related how ZK server deals with client timeout.
