------------------------------------

             Summary: DUCC RM: Never deallocate non-preemptable shares 
                 Key: UIMA-4742
                 URL: https://issues.apache.org/jira/browse/UIMA-4742
             Project: UIMA
          Issue Type: Task
          Components: DUCC
    Affects Versions: 2.0.1-Ducc
            Reporter: Jim Challenger
            Assignee: Jim Challenger
             Fix For: 2.1.0-Ducc


Design change - never deallocate non-preemptable shares until the job is completed in some way.  The shares stay allocated under all these conditions, some of which may require manual attention to clear the job:
- vary off
- node failure
- misconfiguration

Previously, jobs in class FIXED, services, and APs would be purged because they can be started elsewhere.
