Karthik Kambatla commented on YARN-2139:
----------------------------------------
disk-vdisks is one of the ways to represent disk resources, it captures disk
shares for weighted sharing of spinning disks/ SSDs. In the future, we could
add other dimensions like disk-bandwidth, disk-iops, disk-capacity etc. To
specify the dimension(s) to consider for isolation and scheduling, one could
set yarn.nodemanager.resource.disk-dimensions and
yarn.scheduler.disk-dimensions. The design doc -
Disk_IO_Isolation_Scheduling_3.pdf - has more details.

> nodes, (2) isolation at runtime, (3) spindle locality.
