okay youre right guys :... my original thought was : 

- Test if a component is basically functioning before doing deeper tests (i.e. confirm nodemanager is up before running a yarn job).
- then somehow my twisted brain turned that into a *DAG* which is a bit silly. 

Now coming full circle, the purpose of this jira can be fixed, albeit inelegantly, with a simple timeout as [~cos] mentions  :) that should solve the problem for us... leave the fancy test dependency ideas/ pre-testing ideas for another day :)

>             Project: Bigtop
>          Issue Type: Bug
>          Components: tests
>    Affects Versions: 0.8.0

> *Problem* Sometimes YARN jobs can hang indefinetly, and in the case of the {{smoke-tests}} , we also can get an infinite hang it appears.  
> This can be reproduced by simply messing up/deleting the core hadoop components from {{bigtop-deploy/vm/vagrant-puppet}}'s provision script puppet conf file {{provision.sh}}  and running {{vagrant up}}. 
> *Solution* Let add some smarts to the smoke tester - such that the basic yarn services (i.  think hadoop-smoke in test-artifcacts does this maybe ) are confirmed before any yarn based tests are ran.
