[jira] Issue Comment Edited: (HADOOP-5979) Streaming partitioner should allow command, not just Java class

    [ https://issues.apache.org/jira/browse/HADOOP-5979?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12716573#action_12716573 ]

Klaas, could you please shed some light on how you are thinking of implementing this? I guess all what you are saying happens in the framework's PipeMapper, is that right?

> 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.
