> I use the *dynamic executor allocation* function. 
> When an executor is killed, all running tasks on it will be failed. Until reach the maxTaskFailures,
this failed task will re-run with a new task id. 
> But the *ExecutorAllocationManager* won't concern this new tasks to total and pending
tasks, because the total stage task number only set when stage submitted.
