> We often run into cases where we are faced with the option of failing the daemon (fail-fast) vs failing user's work and keep the cluster running. There is no clear right way to handle these situations - some users would like to be conservative and let the daemons run, while others would like to fail-fast. 
> Today, we handle these case-by-case and go by what the people working on it feel is the right way to handle things. Examples include how we handle app recovery failures, queue-changes on RM restart. 
> Users should be able to choose between these two extremes, and have all these situations handled the same way.
