> Key: MESOS-8576
> URL: https://issues.apache.org/jira/browse/MESOS-8576
> Project: Mesos
> Issue Type: Improvement
> Components: containerization, docker
> Affects Versions: 1.5.0
> Reporter: Greg Mann
> Assignee: Greg Mann
> Priority: Major
> Labels: mesosphere
> 
> In the call path of {{Docker::inspect()}}, each continuation currently checks if \
> {{promise->future().hasDiscard()}}, where the {{promise}} is associated with the \
> output of the {{docker inspect}} call. However, if the call to {{docker inspect}} \
> becomes hung indefinitely, then continuations are never invoked, and a subsequent \
> discard of the returned {{Future}} will have no effect. We should add proper \
> {{onDiscard}} handling to that {{Future}} so that appropriate cleanup is performed \
> in such cases.
