Owen O'Malley commented on HADOOP-3150:
---------------------------------------
No, I wouldn't. Partially for backwards compatibility and partially because the
FileOutputCommitter has a more general interface that takes a path. I suggest:
When a FileOutputFormat is configured, get the output directory and the
OutputCommitter. If the OutputCommitter is a FileOutputCommitter, call
setWorkOutputPath with the configuration and the result of
FileOutputPath.getWorkPath(FileOutputFormat.getOutputPath(conf)). Otherwise,
set the work path to the getOutputPath.
