hbase Partitioner for MR Jobs

[Billy Pearson <sa...@pearsonwholesale.com>]

Does anyone out there have any experience writing a hadoop partitioner we 
need on for hbase to split the records from Map outputs
So that all records will for a region will fall in one partition would need 
something that is fast as each output would have to be ran by it

Then if we setup our new TableMapReduceUtil
TableMapReduceUtil.initTableReduceJob(table, reducer, job)
to set the number of reduces to the same number of regions
we could make sure no more then one reduce task was writing
to more then one region at a time.
