> One rack went down today, resulting in one missing block/file.
> Looking at the log, this block was originally over-replicated. 
> 3 replicas on one rack and 1 replica on another.
> Namenode decided to delete the latter, leaving 3 replicas on the same rack.
> It'll be nice if the deletion is also rack-aware.
