Steps to reproduce:
1. Use a workflow that executes distribute-streaming before the Archive step (example:http://opencast.jira.com/wiki/display/MHDOC/Archived+Workflows)
Actual Result: The Workflow fails at the Archive step when streamed RTMP recourse cannot be downloaded.
2. Apply a workflow that executes distribute-streaming after Archive
Actual Result: Archive does not know about the distribute-streaming resource so the resource cannot be retracted
Expected Results: Able to Archive and retract distribute-streaming media
Workaround (if any): Omit the distribute-streaming from Archive operation source-tags so Archive can archive raw media. Manually delete the distribute-streamed resource as necessary.
