> Key: SPARK-11334
> URL: https://issues.apache.org/jira/browse/SPARK-11334
> Project: Spark
> Issue Type: Bug
> Components: Spark Core
> Affects Versions: 1.4.0
> Reporter: meiyoula
> Assignee: meiyoula
>
> 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:
> {code}
> {"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":[]}}
> {code}
> Because that, the *numRunningTasks* in *ExecutorAllocationManager* class will
> be less than 0, and it will affect executor allocation.
