> PigSecondaryKeyComparator does not implement a compare(WritableComparable
> a, WritableComparable b) method. In case of OrderedGroupedMergedKVInput with
> vertex groups, object comparison instead of byte comparison is done when
> merging the multiple inputs into one. Since the compare API is not
> overridden, WritableComparator compare API is called and the value types are
> directly compared which means it is always ascending.
