Quick Start • • • • • • This tutorial provides a quick introduction to using Spark. We will first introduce the API through Spark’s interactive shell (in Python or Scala), then show how to write applications in Java, Scala, and Python. To follow along with this guide, first, download a packaged release of Spark from the. Since we won’t be using HDFS, you can download a package for any version of Hadoop. Note that, before Spark 2.0, the main programming interface of Spark was the Resilient Distributed Dataset (RDD). After Spark 2.0, RDDs are replaced by Dataset, which is strongly-typed like an RDD, but with richer optimizations under the hood.

The RDD interface is still supported, and you can get a more detailed reference at the. However, we highly recommend you to switch to use Dataset, which has better performance than RDD. See the to get more information about Dataset. Interactive Analysis with the Spark Shell Basics Spark’s shell provides a simple way to learn the API, as well as a powerful tool to analyze data interactively. It is available in either Scala (which runs on the Java VM and is thus a good way to use existing Java libraries) or Python. Start it by running the following in the Spark directory. ./bin/spark-shell Spark’s primary abstraction is a distributed collection of items called a Dataset.

Datasets can be created from Hadoop InputFormats (such as HDFS files) or by transforming other Datasets. Let’s make a new Dataset from the text of the README file in the Spark source directory: scala > val textFile = spark. TextFile ( 'README.md' ) textFile: org.apache.spark.sql.Dataset [ String ] = [ value: string ] You can get values from Dataset directly, by calling some actions, or transform the Dataset to get a new one. For more details, please read the.

Scala > textFile. Count () // Number of items in this Dataset res0: Long = 126 // May be different from yours as README.md will change over time, similar to other outputs scala > textFile. First () // First item in this Dataset res1: String = # Apache Spark Now let’s transform this Dataset into a new one. We call filter to return a new Dataset with a subset of the items in the file. Scala > val linesWithSpark = textFile.

Avast cleanup premium torrent. Filter ( line => line. Contains ( 'Spark' )) linesWithSpark: org.apache.spark.sql.Dataset [ String ] = [ value: string ] We can chain together transformations and actions: scala > textFile. Filter ( line => line.

Contains ( 'Spark' )). Count () // How many lines contain 'Spark'? Res3: Long = 15. ./bin/pyspark Or if PySpark is installed with pip in your current environment: pyspark Spark’s primary abstraction is a distributed collection of items called a Dataset. Datasets can be created from Hadoop InputFormats (such as HDFS files) or by transforming other Datasets.
