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. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
