With Crunch versions prior to 0.7.x, there does not appear to be an _SUCCESS 
file written upon completion, starting with 0.7.x there is.  This file (and any 
others not intended to be read through [1]) appears to cause issue with [1].  
This means writing a MapFile with crunch and reading back with [1] works prior 
to 0.7.x, but starting with 0.7.x, [1] will throw an exception.

Is this a bug with Crunch and/or Hadoop?
