In this tutorial, the core concept in Spark,Resilient Distributed Dataset (RDD)will be introduced. RDD is the Spark's core abstraction for working with data. Simply put, an RDD is a distributed collection of elements. In Spark, all work is expressed as either creating new RDDs, transforming...
In this tutorial, we'll learn about Spark and then we'll install it. Also, we're going to see how to use Spark via Scala and Python. For whom likes Jupyter, we'll see how we can use it with PySpark. What is Spark? Apache Spark (http://spark.apache.org/docs/latest/) is a fa...
You need will Spark installed to follow this tutorial. Windows users can check out myprevious post on how to install Spark. Spark version in this post is 2.1.1, and the Jupyter notebook from this postcan be found here. Disclaimer (11/17/18): I will not answer UDF related questions via...
