> Key: HADOOP-450
> URL: http://issues.apache.org/jira/browse/HADOOP-450
> Project: Hadoop
> Issue Type: Improvement
> Components: mapred
> Affects Versions: 0.5.0
> Reporter: Owen O'Malley
> Assigned To: Owen O'Malley
> Fix For: 0.6.0
>
>
> 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.
