Thomas Graves commented on SPARK-11701:

this looks like a dup of SPARK-9038

> I am using dynamic container allocation and speculation and am seeing issues with the
active task accounting.  The Executor UI still shows active tasks on the an executor but the
job/stage is all completed.  I think its also affecting the dynamic allocation being able
to release containers because it thinks there are still tasks.
> Its easily reproduce by using spark-shell, turn on dynamic allocation, then run just
a wordcount on decent sized file and set the speculation parameters low: 
>  spark.dynamicAllocation.enabled true
>  spark.shuffle.service.enabled true
>  spark.dynamicAllocation.maxExecutors 10
>  spark.dynamicAllocation.minExecutors 2
>  spark.dynamicAllocation.initialExecutors 10
>  spark.dynamicAllocation.executorIdleTimeout 40s
> $SPARK_HOME/bin/spark-shell --conf spark.speculation=true --conf spark.speculation.multiplier=0.2
--conf spark.speculation.quantile=0.1 --master yarn --deploy-mode client  --executor-memory
4g --driver-memory 4g
