@pwendell , I just updated the code
In the latest update, I make the checking only applicable to
FileOutputFormat, the difference with your suggestion is that I added checking
for that if the user has set mapred.output.dir, because the internal
implementation of getOutputPath is actually based on this property....
{code}
/**
* Get the {@link Path} to the output directory for the map-reduce job.
*
* @return the {@link Path} to the output directory for the map-reduce
job.
* @see FileOutputFormat#getWorkOutputPath(JobConf)
*/
public static Path getOutputPath(JobConf conf) {
String name = conf.get("mapred.output.dir");
return name == null ? null: new Path(name);
}
{code}
