> First, there is no need to set 'spark.master' multi-times with different values. Second, It is possible for users to set the different 'spark.master' in code with
> `spark-submit` command, and will confuse users. So, we should do once check if the 'spark.master' already exists in settings and if the previous value is the same with current value. Throw a IllegalArgumentException when previous value is different with current value.
