Add streaming config option for not emitting the key ---------------------------------------------------- Key: MAPREDUCE-1785 URL: Project: Hadoop Map/Reduce Issue Type: Improvement Components: contrib/streaming Affects Versions: 0.22.0 Reporter: Eli Collins Assignee: Eli Collins Priority: Minor Fix For: 0.22.0 PipeMapper currently does not emit the key when using TextInputFormat. If you switch to input formats (eg LzoTextInputFormat) the key will be emitted. We should add an option so users can explicitly make streaming not emit the key so they can change input formats without breaking or having to modify their existing programs. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
