    [SPARK-8119][Scheduler]Do not let Spark set total executors when executor 
fails

    `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
