Hi,
I'm new to Spark and Scala as well. I understand that we can use foreach to
apply a function to each element of an RDD, like rdd.foreach
(x=>println(x)), but I saw we can also do a for loop to print each element
of an RDD, like
for (x <- rdd){
println(x)
}
Does defining the foreach function in RDD make an RDD traversable like this?
Does the compiler automatically invoke the foreach function when it sees a
for loop?
Thanks!
Phil
