> Components: mapred

>
> Currently, the application specifies the types of the input keys and values
> and the RecordReader checks them for consistency. It would make more sense to
> have the RecordReader define the types of keys that it will produce.
> Therefore, I propose that we add two new methods to RecordReader:
> WritableComparable createKey();
> Writable createValue();
> Note that I propose adding them to the RecordReader rather than the
> InputFormat, so that they can specific to a particular input split.
