[PATCH] a simple Leader Election or exclusive Write Lock protocol/policy

So having recently discovered ZooKeeper, I'm really liking it - good job folks! I've seen discussions of building high level features from the core ZK library and had not seen any available on the interweb so figured I'd have a try creating a simple one. Feel free to ignore it if a ZK ninja can th

Re: Recipe contrib -- was Re: [PATCH] a simple Leader Election or exclusive Write Lock protocol/policy

As a newbie around hadoop/zookeeper (but long time apache hacker on various things), I think the high level protocol/recipe stuff should definitely be a separate, released module; so folks who wanna use it can share a versioned binary and so forth. It would be awesome to have a few good protocols/r

Re: An interest in increasing the DI'ness of ZooKeeper?

+1 :) I'm a fellow ActiveMQ hacker too and would love to see ZK included with ActiveMQ. Dependency Injection can really help keep your code simple but leaving it flexible so it can be used in many different ways. Here's some links on DI http://martinfowler.com/articles/injection.html http://www.t

I wonder if anyone else has seen this recently; I've been trying to make the WriteLock implementation survive server restarts (i.e. reconnecting to another ZK server) with some success. See the latest patch here... https://issues.apache.org/jira/browse/ZOOKEEPER-78 but I've found I can reliably ge

when should a SessionExpiredException occur?

Am just wondering if I've hit this due to some other bug. I thought ZK did keep-alive pings to ensure each client is alive and its session does not expire? Or does the client have to explicitly keep calling some method on the ZooKeeper interface to ensure a steady flow of packets to the ZK server t
