> Key: TEZ-3990
> URL: https://issues.apache.org/jira/browse/TEZ-3990
> Project: Apache Tez
> Issue Type: Bug
> Affects Versions: 0.9.1, 0.10.0
> Reporter: Kuhu Shukla
> Assignee: Kuhu Shukla
> Priority: Major
> Attachments: TEZ-3990.001.patch, TEZ-3990.002.patch

>
> 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.
