BulkPut - Writable class compatible with TableOutputFormat for bulk puts
agnostic of region server mapping at Mapper/Combiner level
------------------------------------------------------------------------------------------------------------------------------------
Key: HBASE-2368
URL: https://issues.apache.org/jira/browse/HBASE-2368
Project: Hadoop HBase
Issue Type: Improvement
Reporter: Kay Kay
Fix For: 0.21.0
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.
