Aaron Fabbri commented on HADOOP-13631:
---------------------------------------

[~cnauroth] HADOOP-13651 is based on this patch, and I think that this move() 
interface works well in practice.  Checkout my latest patch there for details.

The batch interface used here doesn't appear to be too onerous, and if that 
were the issue in the future, it would be easy to put a single-path move() 
wrapper around the batched move() interface used here.
