Steve Loughran commented on YARN-2139:
--------------------------------------

I'd assumed the vspindles you asked for were == SATA HDD spindles, so on an SSD 
the mapping of  multiple vspindles to a physical one would make sense. And if 
even faster persistent storage/storage interconnect comes out, you'd increase 
the number.

> YARN should consider disk as another resource for (1) scheduling tasks on 
> nodes, (2) isolation at runtime, (3) spindle locality.
