> The OutputFormat API should be changed to be more evolution proof:
> public interface OutputFormatContext {
>   JobConf getJobConf();
>   Progressable getProgress();
> }
> public interface OutputFormat {
>   RecordWriter getRecordWriter(int reduce, OutputFormatContext context) throws IOException;
>   void checkOutputSpecs(OutputFormatContext context) throws IOException;
> }
> And OutputFormatBase would be renamed:
> public abstract class FileOutputFormat implements OutputFormat {
>   protected Path getOutputPath(int reduce, OutputFormatContext context) throws IOException
{ ... }
>   ... current OutputFormatBase methods ...
> }
