Resolution: Fixed
> SimpleDistributedQueue::take() hangs if container nodes are removed
> -------------------------------------------------------------------
>
> 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
> Assignee: Jordan Zimmerman
> Fix For: 3.1.1
>
> Attachments: TestSimpleDistributedQueueHang.java
>
>
> 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.
