Description copied from class: NWritableComparator

Optimization hook. Override this to make SequenceFile.Sorter's scream.

The default implementation reads the data into two NWritableComparables (using NWritable.readFields(DataInput), then calls NWritableComparator.compare(NWritableComparable,NWritableComparable).

Overrides:

compare in class NWritableComparator
