> Ability to kill AM attempts
> ---------------------------
>
> Key: YARN-261
> URL: https://issues.apache.org/jira/browse/YARN-261
> Project: Hadoop YARN
> Issue Type: New Feature
> Components: api
> Affects Versions: 2.0.3-alpha
> Reporter: Jason Lowe
> Attachments: YARN-261--n2.patch, YARN-261--n3.patch, YARN-261.patch

>
> It would be nice if clients could ask for an AM attempt to be killed. This
> is analogous to the task attempt kill support provided by MapReduce.
> This feature would be useful in a scenario where AM retries are enabled, the
> AM supports recovery, and a particular AM attempt is stuck. Currently if
> this occurs the user's only recourse is to kill the entire application,
> requiring them to resubmit a new application and potentially breaking
> downstream dependent jobs if it's part of a bigger workflow. Killing the
> attempt would allow a new attempt to be started by the RM without killing the
> entire application, and if the AM supports recovery it could potentially save
> a lot of work. It could also be useful in workflow scenarios where the
> failure of the entire application kills the workflow, but the ability to kill
> an attempt can keep the workflow going if the subsequent attempt succeeds.
