Apache Spark is an open-source cluster-computing framework. It provides elegant development APIs for Scala, Java, Python, and R that allow developers to execute a variety of data-intensive workloads across diverse data sources including HDFS, Cassandra, HBase, S3 etc. Historically, Hadoop’s MapReduce prooved to be inefficient for some iterative and...
Spark applications run as independent sets of processes on a cluster as described in the below diagram: These set of processes are coordinated by the SparkContext object in your main program (called the driver program). SparkContext connects to several types of cluster managers (either Spark’s own standalone cluster manager, Mesos or YARN), which a...
Now that we understand the core components, we can move on to simple Maven-based Spark project – for calculating word counts. We’ll be demonstrating Spark running in the local mode where all the components are running locally on the same machine where it’s the master node, executor nodes or Spark’s standalone cluster manager.
In this article, we discussed the architecture and different components of Apache Spark. We also demonstrated a working example of a Spark job giving word counts from a file. As always, the full source code is available over on GitHub.
Introduction to Apache Spark With Examples and Use Cases. In this post, Toptal engineer Radek Ostrowski introduces Apache Spark—fast, easy-to-use, and flexible big data processing. Billed as offering “lightning fast cluster computing”, the Spark technology stack incorporates a comprehensive set of capabilities, including SparkSQL, Spark ...

This page shows you how to use different Apache Spark APIs with simple examples. Spark is a great engine for small and large datasets. It can be used with single-node/localhost environments, or distributed clusters. Spark’s expansive API, excellent performance, and flexibility make it a good option for many analyses.
This project contains snippets of Java code for illustrating various Apache Spark concepts. It is intended to help you get started with learning Apache Spark (as a Java programmer) by providing a super easy on-ramp that doesn't involve cluster configuration, building from sources or installing Spark or Hadoop.
