[jira] Updated: (HADOOP-904) OutputFormat should be given the reduce id directly rather than a filename

["Owen O'Malley (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/HADOOP-904?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Owen O'Malley updated HADOOP-904:
---------------------------------

    Description: 
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 ...
}

  was:

public interface OutputFormat {
  RecordReader getRecordReader(int reduce, OutputFormatContext context) throws IOException;
  void checkOutputSpecs(OutputFormatContext context) throws IOException;
