>                 Key: MAPREDUCE-620
>                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-620
>             Project: Hadoop Map/Reduce
>          Issue Type: Improvement
>          Components: contrib/streaming
>            Reporter: arkady borkovsky
>
> For streaming, local execution does not involve hadoop.
> It is just
>   hdfs -cat input | mapper-command | sort | reducer command
> While a user can do this herself, having an option to do this by using the infrastructure would greatly simplify user script and and make it easier to ensure that the process will run on the cluster as expected.
