> Consider the following scenario:
> 1. RM assigns a container on node N to an app A.
> 2. Node N is restarted
> 3. A tries to launch container on node N.
> 3 could lead to an NMNotYetReadyException depending on whether NM N has registered with the RM. In MR, this is considered a task attempt failure. A few of these could lead to a task/job failure.
