Summary: Revisit delay scheduling for cloud environment
Key: YARN-8965
URL: https://issues.apache.org/jira/browse/YARN-8965
Project: Hadoop YARN
Issue Type: Improvement
Reporter: Weiwei Yang
Assignee: Weiwei Yang
Delay scheduling was introduced to honor task locality at best-effort, which
has node/rack level delays. However under cloud environment, usually the
storage is remote to the work-load cluster, which makes the locality constraint
totally irrelevant. Lets revisit this and create a model for cloud environments
without too many setups.
