Summary: [Umbrella] Proposing per-queue Policy driven scheduling in YARN
Key: YARN-3306
URL: https://issues.apache.org/jira/browse/YARN-3306
Project: Hadoop YARN
Issue Type: Bug
Components: scheduler
Reporter: Vinod Kumar Vavilapalli
Assignee: Vinod Kumar Vavilapalli
Scheduling layout in Apache Hadoop YARN today is very coarse grained. This proposal aims at converting today’s rigid scheduling in YARN to a per-queue policy driven architecture.
We propose the creation of a common policy framework and implement acommon set of policies that administrators can pick and chose per queue
- Make scheduling policies configurable per queue
- Initially, we limit ourselves to a new type of scheduling policy that determines the ordering of applications within the leaf queue
- In the near future, we will also pursue parent queue level policies and potential algorithm reuse through a separate type of policies that control resource limits per queue, user, application etc.
