WritableComparator The default implementation uses the natural ordering, calling Comparable.compareTo(Object).

WritableComparatorThe default implementation reads the data into two WritableComparables (using Writable.readFields(DataInput), then calls WritableComparator.compare(WritableComparable,WritableComparable).
