Konstantinos Karanasos updated YARN-4902: ----------------------------------------- Attachment: YARN-5468.prototype.patch We have been working on a first prototype for handling constraints in scheduling. Following [~leftnoteasy]'s recommendation, I am uploading it in this JIRA, as it seems the most related. The patch is by [~pgaref]. This version of the prototype does not include our proposal about *planning* (rather than scheduling) of applications. We plan to update the patch with our proposal. > [Umbrella] Generalized and unified scheduling-strategies in YARN > ---------------------------------------------------------------- > > Key: YARN-4902 > URL: https://issues.apache.org/jira/browse/YARN-4902 > Project: Hadoop YARN > Issue Type: New Feature > Reporter: Vinod Kumar Vavilapalli > Assignee: Wangda Tan > Attachments: Generalized and unified scheduling-strategies in YARN > -v0.pdf, YARN-5468.prototype.patch > > > Apache Hadoop YARN's ResourceRequest mechanism is the core part of the YARN's > scheduling API for applications to use. The ResourceRequest mechanism is a > powerful API for applications (specifically ApplicationMasters) to indicate > to YARN what size of containers are needed, and where in the cluster etc. > However a host of new feature requirements are making the API increasingly > more and more complex and difficult to understand by users and making it very > complicated to implement within the code-base. > This JIRA aims to generalize and unify all such scheduling-strategies in YARN. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: yarn-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: yarn-issues-h...@hadoop.apache.org
