-----------------------------------------
Summary: Containers that never have children stay forever
Key: ZOOKEEPER-3546
URL: https://issues.apache.org/jira/browse/ZOOKEEPER-3546
Project: ZooKeeper
Issue Type: Bug
Components: server
Affects Versions: 3.5.5, 3.5.3
Reporter: Sylvain Wallez
{{ContainerManager}} does not delete containers whose cversion is zero to avoid
situations where a container would be deleted before the application had the
chance to create children.
This caused issues in our application where the process stopped between
container creation and child creation: the containers were never deleted.
To avoid this while giving applications the time to create children, empty
containers with a cversion of zero should be deleted after a grace period, e.g.
not when they are first collected, but the second time.
