----------------------------------
Summary: DUCC Job Driver (JD) fast fail: immediately fetch first
work item to exercise getNext()
Key: UIMA-4854
URL: https://issues.apache.org/jira/browse/UIMA-4854
Project: UIMA
Issue Type: Improvement
Components: DUCC
Reporter: Lou DeGenaro
Assignee: Lou DeGenaro
Fix For: future-DUCC
Presently, the first work item is not fetched from the Collection Reader (CR)
until the first Job Process (JP) successfully initializes and requests same.
For the case where the CR is "bad" (e.g. during development) it would be good
to fail fast, rather than waiting, potentially, for quite a long time for the
first JP to initialize before learning that getNext() is foobar.
