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

So, this isn't as trivial of a change as I had thought:

I'm not sure why it's complaining like this after changing the filesystem impl. I tried to
set {{mapreduce.framework.name=local}} in the configuration, but that doesn't seem to have
made a difference. I'll need to trace through the code to figure out why this isn't just working
in local mode with RawLocalFileSystem as it does with ChecksumFileSystem
