------------------------------------
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.
