> Labels: stale-assigned

> In {{HadoopOutputFormatBase}} open method, the config option
> {{mapreduce.output.basename}} was changed to "tmp" and there is not any
> documentation state this change.
> By default, HDFS will use this format "part-x-yyyyy" to name its file, the x
> and y means :
> * {{x}} is either 'm' or 'r', depending on whether the job was a map only
> job, or reduce
> * {{yyyyy}} is the mapper or reducer task number (zero based)
>
> The keyword "part" has used in many place in user's business logic to match
> the hdfs's file name. So I suggest to revert this config option or document
> it.
