> For users to bulk upload by writing hfiles directly to the filesystem, they 
> currently need to write a partitioner that is intimate with how their key 
> schema works.  This issue is about providing a general partitioner, one that 
> could never be as fair as a custom-written partitioner but that might just 
> work for many cases.  The idea is that a user would supply the first and last 
> keys in their dataset to upload.  We'd then do bigdecimal on the range 
> between start and end rowids dividing it by the number of reducers to come up 
> with key ranges per reducer.
> (I thought jgray had done some BigDecimal work dividing keys already but I 
> can't find it)
