> Key: CURATOR-308
> URL: https://issues.apache.org/jira/browse/CURATOR-308
> Project: Apache Curator
> Issue Type: Bug
> Components: Recipes
> Affects Versions: 3.1.0
> Environment: org.apache.curator:curator-recipes 3.1.0
> org.apache.curator:curator-test 3.1.0
> Reporter: Philip Searle
>
> SimpleDistributedQueue creates the queue using container nodes if the ZooKeeper instance supports this feature. If ZooKeeper runs the container node cleanup task while SimpleDistributedQueue::take() is blocking, the call will not ever return.
> A similar issue occurs when calling poll(), resulting in it delaying until the timeout has elapsed, even if a queue item was inserted after the container cleanup occurs.
