On the list of tougher points about Spark is knowing the scope and everyday living cycle of variables and strategies when executing code throughout a cluster. RDD functions that modify variables outside of their scope can be quite a Repeated source of confusion.
map(func) Return a fresh dispersed dataset formed by passing Just about every component with the source by way of a functionality func.
