----------------------------------------
Summary: Affinity considering cpu vcores when it shouldn't
Key: APEXCORE-783
URL: https://issues.apache.org/jira/browse/APEXCORE-783
Project: Apache Apex Core
Issue Type: Bug
Reporter: Pramod Immaneni
Assignee: Pramod Immaneni
The default yarn scheduler and resource calculator don't include vcores when
allocating containers, they only use memory, but apex's internal affinity
calculator does. This can result in apex not finding containers even though
yarn has them. The vcores should only be included in the affinity calculation
when yarn is using them or instead delegate this completely to yarn.
