Amareshwari Sriramadasu updated MAPREDUCE-605:
----------------------------------------------
Issue Type: New Feature (was: Bug)
> In Streaming, allow different mappers for different subsets of the input
> ------------------------------------------------------------------------
>
> Key: MAPREDUCE-605
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-605
> Project: Hadoop Map/Reduce
> Issue Type: New Feature
> Components: contrib/streaming
> Reporter: arkady borkovsky
>
> The command line may look like this:
> -mapper mapper-command-1 -input dir11 -mapper mapper-command-2 -input dir22
> input -dir21
> meaning that map phase will apply mapper-command-1 to part files from dir11,
> and the part files from dir22 and dir21 will be processed by mapper-command-2
> then all will be shuffled and processed by a single reducer.
