----------------------------------
It would be good to get some feedback on this proposal. Also pinging [~jianhe]
and [~vinodkv] to whom I briefly mentioned this offline.
> AMs only intended to run one attempt can be run more than once

> Key: YARN-5617
> URL: https://issues.apache.org/jira/browse/YARN-5617
> Project: Hadoop YARN
> Issue Type: Bug
> Components: resourcemanager
> Affects Versions: 2.5.0
> Reporter: Jason Lowe
> Assignee: Jason Lowe
> Attachments: YARN-5617.001.patch, YARN-5617.002.patch

> There are times when a user only wants to run an application with one
> attempt. Examples would be cases where the second AM attempt is not prepared
> to handle recovery or will accidentally corrupt state (e.g.: by re-executing
> something from scratch that should not be). Prior to YARN-614 setting the
> max attempts to 1 would guarantee the app ran at most one attempt, but now it
> can run more than one attempt if the attempts fail due to a fault not
> attributed to the application.
