Subject [jira] [Created] (UIMA-5988) UIMA-DUCC: JD fails due to not finding Workitem type in the CAS
Date Thu, 14 Feb 2019 19:37:00 GMT
Jerry Cwiklik created UIMA-5988:

             Summary: UIMA-DUCC: JD fails due to not finding Workitem type in the CAS
                 Key: UIMA-5988
                 URL: https://issues.apache.org/jira/browse/UIMA-5988
             Project: UIMA
          Issue Type: Bug
          Components: DUCC
            Reporter: Jerry Cwiklik
            Assignee: Jerry Cwiklik
             Fix For: 3.0.0-Ducc

The JD throws the following exception:

Feb 14, 2019 9:51:02 AM org.apache.uima.ducc.test.randomsleep.FixedSleepCR getNext(328)
INFO: getNext
org.apache.uima.analysis_engine.AnalysisEngineProcessException: Annotator class org.apache.uima.ducc.CasHelper
requires Type org.apache.uima.ducc.Workitem, which was not found in the CAS.

 at org.apache.uima.ducc.container.jd.cas.CasManager.getMetaCas(CasManager.java:74)


To make things worse the above exception is ignored by JD code and the job continues until
completion giving a false sense of positive completion. The Duccmon shows no errors.

Two fixed needed:

1) Address the missing Workitem type in the cas

2) Improve error handling to detect an exception and cancel a job
