Among the more durable points about Spark is comprehension the scope and existence cycle of variables and procedures when executing code across a cluster. RDD operations that modify variables beyond their scope generally is a Repeated source of confusion.
This merchandise unquestionably gives me an Strength Strengthen, but without the horrible Unintended effects.
