> 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).
