Andrew Purtell commented on HBASE-1963:
---------------------------------------
Kevin,
Patch generally looks good.
HBase expunged all uses of Text in the 0.18 timeframe. Can you use
ImmutableBytesWritable instead?
The example looks great.

> 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.
