----------------------------------
Summary: DUCC Job Driver (JD) erroneously determines: fewer work
items available than expected
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.
