[jira] [Created] (UIMA-2667) DUCC Resource Manager defragmentation problem

Jim Challenger created UIMA-2667:
------------------------------------

             Summary: DUCC Resource Manager defragmentation problem
                 Key: UIMA-2667
                 URL: https://issues.apache.org/jira/browse/UIMA-2667
             Project: UIMA
          Issue Type: Bug
          Components: DUCC
            Reporter: Jim Challenger
            Assignee: Jim Challenger


During defrag a collection of candidate "rich" users and "rich" jobs is made, which forms a collection of candidate shares to evict to make space for NEEDY jobs.  There is a case where a "rich" job may be very rich and yet allocated entirely on machines unsuitable for any NEEDY job.  The bug to fix, is to properly identify this situation and remove the unsuitable shares from consideration.
