> This is due to three different reasons
>  # PRIORITY_FAST_FAIL_MAP priority containers should be considered for reuse.
>  # Whenever CONTAINER_REMOTE_CLEANUP is fired for task attempt, it wont kill 
> current attempt which is assigned to container. That is because task attempt 
> is not updated in ContainerLauncherImpl#Container class. 
>  # Container gets assigned to task attempt even when container has stopped 
> running ie Container completed event is processed. This is because we add 
> reuse container map to allocated list. Makeremoterequest gets the same 
> container in allocationResponse whereas RM has sent same container in 
> finished container list. To avoid this we need to make sure allocated list 
> doesnt have any containers which are finished.
