Description
Currently Map Reduce programs have to use WritableComparable-Writable key-value pairs. While it's possible to write Writable wrappers for other serialization frameworks (such as Thrift), this is not very convenient: it would be nicer to be able to use arbitrary types directly, without explicit wrapping and unwrapping.
