Erwin Tam commented on ZOOKEEPER-886:
-------------------------------------
Bug was an error in the logic of the if condition. For the ZK reconnect
condition, the if logic would bypass the part to change the server back to the
"not suspended" state. Modified this so it will do it correctly now.
> Hedwig Server stays in "disconnected" state when connection to ZK dies but
> gets reconnected

>
> The Hedwig Server is connected to ZooKeeper. In the ZkTopicManager, it
> registers a watcher so that if it ever gets disconnected from ZK, it will
> temporarily fail all incoming requests since the Hedwig server does not know
> for sure if it is still the master for the topics. When the ZK client gets
> reconnected, the logic currently is wrong and it does not unset the suspended
> flag. Thus once it gets disconnected, it will stay in the suspended state
> forever, thereby making the Hedwig server hub dead.
