-------------------------------------

+1 for the current patch.  I reapplied the patch and reran the new tests successfully.  Thanks
for addressing the feedback.  It looks great.

> HDFS-1120 introduced pluggable block-volume choosing policies, but still carries the
vanilla RoundRobin as its default.
> An additional implementation that also takes into consideration the free space remaining
on the disk (or other params) should be a good addition as an alternative to vanilla RR.
