> Clean up RuntimeException code in AMReporter

>             Project: Hive
>          Issue Type: Bug
>          Components: llap
>    Affects Versions: 3.1.1
>            Reporter: Oliver Draese
>            Assignee: Oliver Draese
>            Priority: Major
> The AMReporter of LLAP throws RuntimExceptions from within addTaskAttempt and 
> removeTaskAttempt. These can cause LLAP to come down.
> As an interims fix (see HIVE-22113), the RuntimeException of removeTaskAttemp 
> is caught from within TaskRunnerCallable, preventing LLAP termination if a 
> killed task is not found in AMReporter.
> Ideally, we would just log this on removeTask (a gone task is a gone task) 
> and have a checked exception in addTaskAttempt. If the checkedException is 
> caught, we should fail the task attempt (as there is already an attempt with 
> this ID running).
