-- | Requests that the status of the specified physical or logical pipeline
-- objects be updated in the specified pipeline. This update might not occur
-- immediately, but is eventually consistent. The status that can be set depends
-- on the type of object (for example, DataNode or Activity). You cannot perform
-- this operation on 'FINISHED' pipelines and attempting to do so returns 'InvalidRequestException'.
