Subject Re: how to set zookeeper session time to forever?
Date Wed, 07 Dec 2011 21:23:47 GMT
The client bindings are responsible for maintaining a heartbeat with
the service:
http://zookeeper.apache.org/doc/r3.3.4/zookeeperProgrammers.html#Java+Binding
there's nothing you need to do here from your application's
perspective. If the TCP connection is lost btw the client and server
(or any other reason why the client's heartbeats don't get to the
server and back, such as a GC pause on the client side) that's when
the timeout comes into play.
