we wanted to present the most comprehensive book on Apache Spark, covering all of the fundamental use cases with easy-to-run examples. Second, we especially wanted to explore the higher-level “structured” APIs that were finalized in Apache Spark 2.0—namely DataFrames, Datasets, Spark SQL, and Structured Streaming—which older books on ...
Nov 1, 2019 · According to Shaikh et al. (2019), Apache Spark is a sophisticated Big data processing tool that uses a hybrid framework. Furthermore, according to Shaikh et al. (2019), Apache Spark is a...
Oct 13, 2016 · In this paper, we present a technical review on big data analytics using Apache Spark. This review focuses on the key components, abstractions and features of Apache Spark. More specifically, it shows what Apache Spark has for designing and implementing big data algorithms and pipelines for machine learning, graph analysis and stream processing.

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.
A thorough and practical introduction to Apache Spark, a lightning fast, easy-to-use, and highly flexible big data processing engine.
