-- Cancels a job in an Batch job queue. Jobs that are in the @SUBMITTED@,
-- @PENDING@, or @RUNNABLE@ state are canceled. Jobs that progressed to the
-- @STARTING@ or @RUNNING@ state aren\'t canceled. However, the API
-- operation still succeeds, even if no job is canceled. These jobs must be
-- terminated with the TerminateJob operation.
