>   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.
