> Key: IGNITE-7090
> URL: https://issues.apache.org/jira/browse/IGNITE-7090
> Project: Ignite
> Issue Type: Bug
> Components: cache, data structures
> Affects Versions: 2.1, 2.4
> Reporter: Tim Onyschak
> Assignee: Tim Onyschak
> Priority: Major
> Fix For: 2.5
>
> Attachments: SemaphoreFailoverNoWaitingAcquirerTest.java
>
>
> If no acquirers are available to take permit of semaphore, the permit never
> gets release and any further acquirerers will wait forever.
> On node shut down DataStructuresProcessor.dsMap gets cleared out prior to
> event listener being able to execute onNodeRemoved, hence owner is never
> cleared out if it was unable to pass to a different acquirer.
