Subject [jira] [Commented] (YARN-2745) Extend YARN to support multi-resource packing of tasks
Date Wed, 17 Jun 2015 23:39:05 GMT

    [ https://issues.apache.org/jira/browse/YARN-2745?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14590858#comment-14590858

Karthik Kambatla commented on YARN-2745:
----------------------------------------

YARN-3332 tracks the work required to move all this collection from within Yarn to a service
that HDFS could also use. We are just getting the collection bits in first, and plan to consolidate
and move things around after.

> In this umbrella JIRA we propose an extension to existing scheduling techniques, which
accounts for all resources used by a task (CPU, memory, disk, network) and it is able to achieve
three competing objectives: fairness, improve cluster utilization and reduces average job
completion time.
