There are two types of Spark RDD Operations which can be performed on the created datasets:Īctions: It is used to perform certain required operations on the existing datasets. Scala> val newRDD = oddnum.map(value => (value * 2)) Value: .RDD = ParallelCollectionRDD at parallelize at :26 Scala> val value = sc.parallelize(oddnum) Here sc is called the object of SparkContext.Įxamplefile: .RDD = file.txt MapPartitionsRDD at textFile at :24ī) An RDD can be created through Parallelized Collection as follows: Scala> val examplefile = sc.textFile("file.txt") All the datasets of RDD are partitioned logically across multiple nodes of a cluster.Īn RDD can be created only by reading from a local file system or by transforming an existing RDD.Ī) To create a new RDD we use the following command: The basic data structure of Spark is called an RDD (Resilient Distributed Datasets) which contains an immutable collection of objects for distributed computing of records.
