> TableOutputFormat currently accepts only a put/delete as writables. Some mapper processes might want to consolidate the 'put's and insert them in bulk. Useful in combiners / mappers - to send across a bunch of puts from one stage to another , while maintaining a very similar region-server-mapping agnostic api at respective levels. 
> New type - BulkPut ( Writable ) introduced that is just a consolidation of Puts.  Eventually , the TableOutputFormat bulk inserts the puts together into the hbase eco-system. 
> Patch made against trunk only. But since , it does not break any backward compatibility - it can be an useful addition to the branch as well. 
> Let me know your comments on the same.
