> DynamicAllocation will set the total executor to a little number when it 
> wants to kill some executors.
> But in no-DynamicAllocation scenario, Spark will also set the total executor.
> So it will cause such problem: sometimes an executor fails down, there is no 
> more executor which will be pull up by spark.
