> o.a.h.h.mapreduce.TableOutputFormat allows writing to a single table as output from a map/reduce job in the natural way. It requires that the user specify the table name ahead of time and can only write to one table. I had a need to write to multiple tables from the same job (write my data to one table, and also write to index tables), and I wanted to have a consistent API whether writing to one or many tables.
> Attached MultiTableOutputFormat takes the table name as the key and the Put or Delete as the value. Also included is an example demonstrating the usage.
