Saisai Shao commented on SPARK-7699:
------------------------------------

Yes, you are right after checking the code of {{addExecutors}}. But not sure if 
load is less, choose {{minNumExecutors}} is the design intention? If so, then 
there's no bug here.

> Config "spark.dynamicAllocation.initialExecutors" has no effect
