> We currently provide InputFormats for reading from Accumulo and output formats for both
direct input as well as outputting RFiles. But we provide no mechanism for doing a mapreduce
over existing RFiles, which may be useful for optimizing data flow. We already have input
formats which use RFiles directly for input (The offline input format Keith just finished),
but that still relies on the Accumulo structure. We should go ahead and also create an input
format that just hits RFiles like the other standard file input formats.
