> Deadlock when terminating ZooKeeperProcess

> Key: MESOS-1477

> Project: Mesos
> Issue Type: Bug
> Reporter: Vinod Kone

>
> (1) ZooKeeper callback in progress, calls ZooKeeperProcess::event.
> (2) ZooKeeperProcess::event calls ProcessWatcher::process.
> (3) ProcessWatcher::process calls zk->getSessionId().
> (4) This dispatches onto ZooKeeperProcess and blocks.
> If in between (1) and (4) there is a termination of the ZooKeeperProcess then
> (4) will block forever because the dispatch event will be dropped. This means
> that the zookeeper thread is blocked and zookeeper_close could block forever!
> This was introduced when the session id was added to all the dispatches
> inside WatcherProcess.
