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

             Summary: DUCC: RM allow "hostile" jobs that don't share resources with others
                 Key: UIMA-4256
                 URL: https://issues.apache.org/jira/browse/UIMA-4256
             Project: UIMA
          Issue Type: Improvement
          Components: DUCC
    Affects Versions: 1.1.0-Ducc
            Reporter: Jim Challenger
            Assignee: Jim Challenger
             Fix For: 2.0.0-Ducc


Certain types of jobs will consume every processor on a host regardless of the memory assignment.  This update allows the declaration of a "hostile" flag in a FAIR_SHARE class definition that instructs the RM not to schedule other work on any processor with a job submitted to a hostile class.  If this is done, the full share count of each host is accounted under the user's fair-share allocation regardless of the memory declaration.
