Steve Loughran commented on YARN-3337:
--------------------------------------

great to hear support. I'm thinking we may want to simulate the failure causes 
too, to include pre-emption and out of pmem/vmem to see how apps handle that

> Provide YARN chaos monkey

>                 URL: https://issues.apache.org/jira/browse/YARN-3337
>             Project: Hadoop YARN
>          Issue Type: New Feature
>          Components: test
>    Affects Versions: 2.7.0
>            Reporter: Steve Loughran

> To test failure resilience today you either need custom scripts or implement 
> Chaos Monkey-like logic in your application (SLIDER-202). 
> Killing AMs and containers on a schedule & probability is the core activity 
> here, one that could be handled by a CLI App/client lib that does this. 
> # entry point to have a startup delay before acting
> # frequency of chaos wakeup/polling
> # probability to AM failure generation (0-100)
> # probability of non-AM container kill
> # future: other operations
