             Summary: DUCC RM should reap non-preemptable shares for services, jobs, and AP
                 Key: UIMA-3614
                 URL: https://issues.apache.org/jira/browse/UIMA-3614
             Project: UIMA
          Issue Type: Improvement
          Components: DUCC
            Reporter: Jim Challenger
            Assignee: Jim Challenger


Original DUCC design said that non-preemptable shares could never be deallocated by RM unless the owner canceled the work running in those shares, even if the underlying system fails.

Since then, job-jobs, services, and "managed reservations" have been defined to run in non-preemptable shares.

If RM detects node failure it should now include non-preemptable shares in the reaper, as long as the shares are occupied by job-jobs, services, and MRs.  "Unmanaged"-reservations continue to remain allocated forever, or until the owner releases them.
