--------------------------------------

I think you are looking at a non-trunk version. In trunk, TableOutputFormat seems to use the new mapreduce classes (and extend OutputFormat<KEY, Writable>)

> There should be no use of classes from o.a.h.mapred in o.a.h.h.mapreduce, only the classes in o.a.h.mapreduce. To do so invites problems by mixing compatibility mode with the >= 0.20 mapreduce classes.

> {code}
> import org.apache.hadoop.mapred.JobConf;
> import org.apache.hadoop.mapred.FileOutputFormat;
> public class TableOutputFormat extends

> bq. Notice that TableOutputFormat extends the old (mapred) FileOutputFormat and thus the old OutputFormat.
