> Add  OutputFormat methods like:
> /** Called to initialize output for this job. */
> void initialize(JobConf job) throws IOException;
> /** Called to finalize output for this job. */
> void commit(JobConf job) throws IOException;
> In the base implemenation for FileSystem output, initialize() might then create a temporary
directory for the job, removing any that already exists, and commit could rename the temporary
output directory to the final name. 
> The existing checkOutputSpecs() would continue to throw an exception if the final output
already exists.
