Subject Re: Hadoop Binary File

I'm also doing binary image processing on Hadoop.  Where relevant, my Key and Value types are
a WritableComparable class of my own creation which contains as members a BytesWritable object,
obviously read from the file itself directly into memory.  I also keep the path in my class
so I know where the file came from later.
