Cancels a job in an Batch job queue. Jobs that are in the SUBMITTED or PENDING are canceled. A job inRUNNABLE remains in RUNNABLE until it reaches the head of the job queue. Then the job status is updated to FAILED.

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.
