Karthik Kambatla commented on YARN-2745:

Read the paper and synced up with Srikanth, Robert and Ganesh offline. 

The work is indeed something we should definitely get into YARN - preferably 
into both capacity and fair schedulers, instead of a completely new scheduler. 
Srikanth and Robert have offered to post a design document, that summarizes the 
changes (more concise than in the paper). AFAICT, bulk of the work is 
scheduler-agnostic and the scheduler-specific parts could be implemented 
separately for the two schedulers.

> 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.
