> Key: UIMA-4938
> URL: https://issues.apache.org/jira/browse/UIMA-4938
> Project: UIMA
> Issue Type: Bug
> Components: DUCC
> Reporter: Lou DeGenaro
> Assignee: Lou DeGenaro
> Fix For: 2.1.0-Ducc
>
>
> Seemingly a rare event: all work items were successful yet ducc.log contents:
> 2016.05.18 10:23:18 Wed Received
> 2016.05.18 10:23:18 Wed WaitingForDriver
> 2016.05.18 10:23:32 Wed WaitingForServices
> 2016.05.18 10:23:39 Wed WaitingForResources
> 2016.05.18 10:24:29 Wed Assigned
> 2016.05.18 10:24:34 Wed Initializing
> 2016.05.18 10:25:06 Wed Running
> 2016.05.18 10:27:49 Wed Completing
> 2016.05.18 10:28:55 Wed Completed
> 2016.05.18 10:28:55 Wed completion type: CanceledByDriver
> 2016.05.18 10:28:55 Wed rationale: fewer work items available than expected
> JobDriver ActionGet needs synchronization to prevent overlapping JP requests
> from processing partially updated information and thereby arriving at an
> incorrect conclusion.
