Hello, I am wondering what will happen if I use a reference for transforming
rdd, for example:
def func1(rdd: RDD[Int]): RDD[Int] = {
rdd.map(x => x * 2) // example transformation, but I am using a more
complex function
}
def main() {
.....
val myrdd = sc.parallelize(1 to 1000000)
val myrdd2 = func1(myrdd)
myrdd2.count()
}
The above is just an example. I am wondering if it is safe to use reference
like this. Thank you.
