[jira] [Commented] (YARN-2745) YARN new pluggable scheduler which does multi-resource packing

    [ https://issues.apache.org/jira/browse/YARN-2745?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14184506#comment-14184506 ] 

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

That is pretty interesting work. Thanks for filing this JIRA, [~rgrandl]

FairScheduler allows setting a different policy per queue. Given fairness is one of your criteria, did you consider adding a policy to the FairScheduler instead of a completely new scheduler?

> In this umbrella JIRA we propose a new pluggable scheduler, 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.
