People are at the heart of customer success and with training and certification through Databricks Academy, you will learn to master data analytics from the team that started the Spark research project at UC Berkeley.

It employs a NameNode and DataNode architecture to implement a c distributed file system that provides high-performance access to data across highly scalable. At its outset, it was closely coupled with MapReduce, a programmatic framework for data processing.

The company founded by the creators of Spark — Databricks — summarizes its functionality best in their Gentle Intro to Apache Spark eBook highly recommended read - link to PDF download provided at the end of this article :. As of the time of this writing, Spark is the most actively developed open source engine for this task; making it the de facto tool for any developer or data scientist interested in Big Data.

Spark supports multiple widely used programming languages Python, Java, Scala, and R , includes libraries for diverse tasks ranging from SQL to streaming and machine learning, and runs anywhere from a laptop to a cluster of thousands of servers. This makes it an easy system to start with and scale up to Big Data processing on an incredibly large scale. Based on my pre l iminary research, it seems there are three main components that make Apache Spark the leader in working efficiently with Big Data at scale, which motivate a lot of big companies working with large amounts of unstructured data, to adopt Apache Spark into their stack.

The short answer is — it depends on the particular needs of your business, but based on my research, it seems like 7 out of 10 times the answer will be — Spark. Linear processing of huge datasets is the advantage of Hadoop MapReduce, while Spark delivers fast performance , iterative processing, real-time analytics, graph processing, machine learning and more. So, when the size of the data is too big for Spark to handle in memory, Hadoop can help overcome that hurdle via its HDFS functionality.

Below is a visual example of how Spark and Hadoop can work together:. Apache Spark is the uncontested winner in this category. With the massive explosion of Big Data and the exponentially increasing speed of computational power, tools like Apache Spark and other Big Data Analytics engines will soon be indispensable to Data Scientists and will quickly become the industry standard for performing Big Data Analytics and solving complex business problems at scale in real-time.

When the volume of data is too high to process and analyze on a single machine, Apache Spark and Apache Hadoop can simplify the task through parallel processing and distributed processing. The high-velocity at which big data is generated requires that the data also be processed very quickly and the variety of big data means it contains various types of data, including structured, semi-structured, and unstructured data [4]. The volume, velocity, and variety of big data calls for new, innovative techniques and frameworks for collecting, storing, and processing the data, which is why Apache Hadoop and Apache Spark were created. Understanding what parallel processing and distributed processing is will help to understand how Apache Hadoop and Apache Spark are used in big data analytics.
