> Troubleshooting YARN problems can be difficult on a production environment.
> Collecting data before problems occur or actively collecting data in an on-demand basis could truly help tracking down issues.
> Some examples: 
> 1. If application is hanging, application logs along with RM / NM logs could be collected, plus jstack of either the YARN daemons or the application container.
> 2. Similarly, when an application fails we may collect data.
> 3. Scheduler issues are quite common so good tooling that helps to spot issues would be crucial.
> Design document will be added later.
