Vinod Kumar Vavilapalli updated YARN-3306: ------------------------------------------ Attachment: PerQueuePolicydrivenschedulinginYARN.pdf Here's a detailed proposal doc. It's light on details on the leaf-queue policy interface - will do so in one of the sub-tasks. [~cwelch] is helping with most of the implementation, Tx Craig. > [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 > Attachments: PerQueuePolicydrivenschedulinginYARN.pdf > > > 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)
