Karthik Kambatla commented on YARN-2817:
----------------------------------------

Resolving this as a duplicate of YARN-2791 since that JIRA proposes the exact 
same thing. In any case, I think these should be subtasks for YARN-2139, 
looking at the prototype code posted there.

> As YARN continues to cover new ground in terms of new workloads, disk is 
> becoming a very important resource to govern.
> It might be prudent to start with something very simple - allow applications 
> to request entire drives (e.g. 2 drives out of the 12 available on a node), 
> we can then also add support for specific iops, bandwidth etc.
