Ways to create RDD in Apache Spark

Question

I'm new to Apache Spark and I want to create RDD so, I saw somewhere that there are 2 ways to create RDD. Can anyone tell me what are the 2 ways and how to create RDD using both the ways?

Answer 1

There are two popular ways using which you can create RDD in Apache Spark.

First is Parallelize and other is text File method. Here is quick explanation how both methods can be used for RDD creation.

val a= Array(5,7,8,9)
val b= sc.parallelize(a)
val c = sc.textFile(“demo.txt”);

Hope you got the answer.
