> Key: MAPREDUCE-238

> Project: Hadoop Map/Reduce
> Issue Type: Improvement

> 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 ...
> }
