Subject [jira] [Commented] (YARN-3337) Provide YARN chaos monkey
Date Sat, 14 Mar 2015 21:46:39 GMT

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

> 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
