Varun Vasudev commented on YARN-2618:
-------------------------------------
[~ywskycn] - can you please think about changing 'vdisks' to something that
reflects that it is a weighted number? Something like 'weighted-disk-io'. The
term vdisks intuitively seems to imply a spindle with the 'v' meaning that we
don't know if it's SSD or a SATA drive.
