Devendra Bhat commented on MAPREDUCE-614:
-----------------------------------------
I don't know most of the thing which you guys were saying but I want to express
clearly what thing I want from this partitioner function.
I have been trying to study mapreduce with python and while using python I have
to pass the python codes as command.
Can you please implement what you suggested about this "it might be easier to
define a suitable partitioner command (when using shell tools it might be
easier to output a string instead of a specific number for example)," as
@Klass suggested above.
> Streaming partitioner should allow command, not just Java class

> Key: MAPREDUCE-614
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-614
> Project: Hadoop Map/Reduce
> Issue Type: Bug
> Components: contrib/streaming
> Reporter: Klaas Bosteels
>
> Since HADOOP-4842 got committed, Streaming allows both commands and Java
> classes to be specified as mapper, reducer, and combiner, but the
> {{-partitioner}} option is still limited to Java classes only. Allowing
> commands to be specified as partitioner as well would greatly improve the
> flexibility of Streaming programs.
