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.
