You can pass the buck and say we're not gonna allow the ZooKeeper to reconnect. Then say we're not allowed to have the WriteLock reconnect, then the next and next layer of the onion. But eventually there's gonna be something somewhere that recreates a session :) For now I'll work on the assumption we're gonna have to have an object which is a wrapper around a ZooKeeper so that it can handle reconnections by just discarding one ZooKeeper instance and creating another. This object could be shared across Protocols (we might wanna reuse one connection with ZK to make multiple locks for example). provide a mechanism to reconnect a ZooKeeper if a client receives a SessionExpiredException --- Key: ZOOKEEPER-84 URL: https://issues.apache.org/jira/browse/ZOOKEEPER-84 Project: Zookeeper Issue Type: Improvement Components: java client Reporter: james strachan Assignee: james strachan Attachments: reconnect_patch.patch am about to attach a patch which adds a reconnect() method to easily re-establish a connection if a session expires - along with a toString() implementation for easier debugging -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
