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.
