-- 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'.
