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.
> YARN new pluggable scheduler which does multi-resource packing

> Key: YARN-2745
> URL: https://issues.apache.org/jira/browse/YARN-2745

> Issue Type: Improvement
> Components: resourcemanager, 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.
