------------------------------------
> Clean up RuntimeException code in AMReporter
> --------------------------------------------
>
> Key: HIVE-22117
> URL: https://issues.apache.org/jira/browse/HIVE-22117
> 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).
