Allen Wittenauer resolved MAPREDUCE-620.
----------------------------------------
Resolution: Won't Fix
Unix already provides this functionality.
> Streaming: support local execution
> ----------------------------------
>
> 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.
