[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=14212586#comment-14212586 ] 

Srikanth Kandula commented on YARN-2745:
----------------------------------------

Thanks Karthik, that is an interesting thought. It seems that several of the proposed work-items (resource estimation, expanded asks, modifications to task matching on NM hearbeat) have to happen regardless of whether this is a new scheduler or a flag atop existing ones like FairScheduler. Do you foresee any additional complications to build this as a flag as opposed to stand-alone? Will take this offline.

> 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.
