[jira] [Resolved] (UIMA-4256) DUCC: RM allow "hostile" jobs that
don't share resources with others
[ https://issues.apache.org/jira/browse/UIMA-4256?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Jim Challenger resolved UIMA-4256.
----------------------------------
Resolution: Won't Fix
On more discussion we realized that we could use cgroups to limit CPU usage so jobs don't become "hostile." No need to modify RM.

> 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.
