Owen O'Malley commented on HADOOP-611:
--------------------------------------
I think the interface should look like:
public interface KeyValueIterator<Key extends Writable, Value extends Writable>
{
boolean next(Key key, Value value);
}
and in SequenceFile.Sorter:
<Key extends WritableComparable, Value extends Writable>
KeyValueIterator<Key,Value>
merge(File[] inFiles, boolean deleteInput) throws IOException {...}
which merges the list of files into an iterator.
> SequenceFile.Sorter should have a merge method that returns an iterator

> SequenceFile.Sorter should get a new merge method that returns an iterator

> The current merge method should become a simple method that gets the iterator
