For the following is an enhancement or bug fix needed?

 When using map class:  TableMapper<ImmutableBytesWritable, IntWritable> 
 
 with reduce class:  TableReducer<ImmutableBytesWritable, IntWritable, 
ImmutableBytesWritable> 

the  order of Iterable<IntWritable> values passed to the reducer from the 
mapper is not preserved in a small percentage of cases.

--------------------------------------------------------------------------------------

Suggestion:  Guaranteeing the chronological order of receipt by the reducer as 
per the order written to the context by the mapper would give helpful and 
simple facility for identification purposes to the reducer.
