One of many more difficult factors about Spark is being familiar with the scope and everyday living cycle of variables and techniques when executing code across a cluster. RDD operations that modify variables outside of their scope can be a Regular supply of confusion.
Generally, closures - constructs like loops or locally outlined strategies, shouldn't be accustomed to mutate some world-wide condition. Spark does not define or assure the habits of mutations to things referenced from beyond closures.
