 Just sort of thinking "out loud".
> I was thinking about how file recovery works on services like Usenet to fix data corruption
when chunks of files are missing.  I wonder how hard it would be to implement something like
PAR2 [ http://en.wikipedia.org/wiki/Parchive ] automatically for large files.  We'd have the
advantage of being able to do it in binary of course and could likely hide the details within
HDFS itself.
