Mike Drob commented on CURATOR-134:
-----------------------------------
It might be worth clarifying the docs to be more explicit about the semantics
of connection v session loss.
> Curator sends a connection LOST event before sessionTimeout
> -----------------------------------------------------------
>
> Key: CURATOR-134
> URL: https://issues.apache.org/jira/browse/CURATOR-134
> Project: Apache Curator
> Issue Type: Bug
> Components: Client
> Affects Versions: 2.6.0
> Environment: Ubuntu 12.04
> Reporter: Benjamin Jaton
> Priority: Critical
> Attachments: Test.java
>
>
> Created a Curator client with:
> - connection timeout: 10 seconds
> - session timeout: 30 seconds
> - retry policy: RetryNTimes(3, 10000)
> A scenario where the ensemble is lost produces the the curator client to send
> a LOST event in less than the expected 30 seconds:
> Fri Aug 01 11:17:19 PDT 2014 - CURATOR STATE: SUSPENDED
> Fri Aug 01 11:17:29 PDT 2014 - CURATOR STATE: LOST
> The client code is attached, this is the complete output:
> Fri Aug 01 11:16:53 PDT 2014 - CURATOR STATE: CONNECTED
> Fri Aug 01 11:16:54 PDT 2014 - Creating ZK client...
> Fri Aug 01 11:16:54 PDT 2014 - ZK client created...
> Fri Aug 01 11:16:54 PDT 2014 - ZOOKEEPER STATE: SyncConnected
> Fri Aug 01 11:16:58 PDT 2014 - ZOOKEEPER STATE: Disconnected
> Fri Aug 01 11:16:58 PDT 2014 - CURATOR STATE: SUSPENDED
> Fri Aug 01 11:17:16 PDT 2014 - CURATOR STATE: RECONNECTED
> Fri Aug 01 11:17:17 PDT 2014 - ZOOKEEPER STATE: SyncConnected
> Fri Aug 01 11:17:19 PDT 2014 - ZOOKEEPER STATE: Disconnected
> Fri Aug 01 11:17:19 PDT 2014 - CURATOR STATE: SUSPENDED
> Fri Aug 01 11:17:29 PDT 2014 - CURATOR STATE: LOST
> I think that the LOST event is actually 30 seconds away from the very first
> SUSPENDED event, whereas is should be 30 seconds away from the last one.
> To reproduce it, I started only 2 ZK servers in a 3 nodes ensembles, then I
> stopped one of them (-> 1st SUSPENDED), waited for 10-20 seconds, then
> started it and stopped it again.
