>             Project: Hadoop Map/Reduce
>          Issue Type: Improvement
>          Components: contrib/streaming
>            Reporter: arkady borkovsky
>
> Some streaming commands in map or reduce phase, as a "side effect", produce 
> several output files.
> The names of output files may be hard coded, or specified on the command line.
> Streaming infrastructure should allow to get these files copied into DFS. 
> For each distinct "output file name", a separate DFS dataset (DFS directory) 
> should be created, and a file of an individual task should be stored there as 
> a part file.   The names of directories may be derived from the main "output 
> name" (default)
> Related to https://issues.apache.org/jira/browse/HADOOP-2236:  in case of 
> reduce, a single name output file may be seen as a special case if this.
