> In a scenario where the same mapId fetches fail, the penalty code allows adding the same
Host/InputAttemptIdentifier over and over with revised penalty time that grows exponentially.
It should at some point drop the retrying and report failure to the AM asap to allow the job
to rectify the upstream output.
