> With *Dynamic Allocation* function, a task failed over *maxFailure* time, all the dependent
jobs, stages, tasks will be killed or aborted. In this process, *SparkListenerTaskEnd* event
will be behind in *SparkListenerStageCompleted* and *SparkListenerJobEnd*. Like the Event
Log below:
> {quote}
> {"Event":"SparkListenerStageCompleted","Stage Info":{"Stage ID":20,"Stage Attempt ID":0,"Stage
Name":"run at AccessController.java:-2","Number of Tasks":200}
> {"Event":"SparkListenerJobEnd","Job ID":9,"Completion Time":1444914699829}
> {"Event":"SparkListenerTaskEnd","Stage ID":20,"Stage Attempt ID":0,"Task Type":"ResultTask","Task
End Reason":{"Reason":"TaskKilled"},"Task Info":{"Task ID":1955,"Index":88,"Attempt":2,"Launch
Time":1444914699763,"Executor ID":"5","Host":"linux-223","Locality":"PROCESS_LOCAL","Speculative":false,"Getting
Result Time":0,"Finish Time":1444914699864,"Failed":true,"Accumulables":[]}}
> {quote}
> Because that, the *numRunningTasks* in *ExecutorAllocationManager* class will be less
than 0, and it will affect executor allocation.
