-------------------------------------------------
Summary: Short-circuit preemption filtering when a Veto applies to
entire host
Key: AURORA-1908
URL: https://issues.apache.org/jira/browse/AURORA-1908
Project: Aurora
Issue Type: Task
Reporter: Santhosh Kumar Shanmugham
Priority: Minor
When matching a {{ResourceRequest}} against a {{UnusedResource}} in
{{SchedulerFilterImpl.filter}} there are 4 kinds of {{Veto}}es that can be
returned. 3 out of the 4 {{Veto}}es apply to the entire host (namely
{{DEDICATED_CONSTRAINT_MISMATCH}}, {{MAINTENANCE}}, {{LIMIT_NOT_SATISFIED}} or
{{CONSTRAINT_MISMATCH}}). In this case we can short-circuit and return early
and move on to the next host to consider.
