     [ https://issues.apache.org/jira/browse/MAPREDUCE-6200?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Kengo Seki reassigned MAPREDUCE-6200:

    Assignee: Kengo Seki

I think -mapper is also optional. I'd like to fix the document.

> -reducer is listed as a Required option, but is a -reducer still required if the Streaming job is Map only?
> http://hadoop.apache.org/docs/r1.2.1/streaming.html#Specifying+Map-Only+Jobs
> -reducer should not be listed as a Required option.
