Apache Spark, more commonly known as Spark, has been adopted by enterprises across a wide range of industries. Get tuned here to learn about the best Spark Tutorials.
Internet powerhouses such as Netflix, Yahoo, and eBay have already deployed Spark. These are collectively processing multiple petabytes of data on clusters of over 8,000 nodes.
Spark tutorial is becoming increasingly popular among developers across the world. It has largely contributed to the largest open source community in big data, with over 1000 contributors from 250+ organizations.
In this apache spark tutorial blog, we will discuss in detail the importance of Spark tutorials. We’ll learn more about the best apache-spark tutorials to choose from, and what you can learn from them.
Apache Spark is a fast, in-memory data processing engine with elegant and expressive development APIs. This allows data workers to efficiently execute streaming, machine learning or SQL workloads. The requirement is fast iterative access to datasets.
By taking a Spark tutorial you can learn how Spark runs on Apache Hadoop YARN. Further, you can create applications derive insights, and lessen data science workloads within a single, shared dataset in Hadoop.
What is Apache Spark?
Apache Spark, widely known as a lightning-fast cluster computing designed for fast computation was built on top of Hadoop MapReduce. It extends the MapReduce model to efficiently use more types of computations which includes Interactive Queries and Stream Processing.
Spark was developed as one of Hadoop’s subproject in 2009 at UC Berkeley’s AMPLab by MateiZaharia. It was Open Sourced in the following year under a BSD license. Later Spark was donated to Apache software foundation. Today Apache Spark stands as of the top-level Apache projects since February 2014.
Spark 2.0 is already available for use as a preview and a full release will happen soon. This will ensure a real step forward with the unification of datasets and data frames.
The Hadoop YARN-based architecture that provides a foundation that enables Spark and other applications to share a common cluster and dataset. In the backend, it must ensure consistent levels of service and response. Spark is now one of many data access engines that work with YARN in HDP.
Why is Apache Spark Tutorial so important?
Prerequisites
So, you are all set to take up a Spark Tutorial. If you have prior exposure to Scala programming, database concepts, and any of the Linux operating system flavors. This is the best career decision for you. Even if you have a programming or a mathematics background, you can enroll for an Apache Spark tutorial as well.
What do you learn in a typical Apache Spark Tutorial?
Most Adobe Spark Tutorials gives you an overview of Spark in Big Data. Thereafter, you will be formally introduced to Apache Spark Programming. The fundamental of Spark components are of primal importance in Apache Spark Tutorial. In addition, you will also learn about Spark’s core abstraction and Spark RDD. Almost all Apache Spark Tutorials cover spark features, Spark limitations, and Spark Use cases.
While choosing a Spark Tutorial, make sure the course includes the following:
Spark Tutorial: Apache Spark Components
Spark Core
Spark Core which is of pivotal importance in any Spark tutorial provides an execution platform for all the Spark applications. In addition, Spark offers a generalized platform for a wide array of applications, a major advantage of using Spark.
Spark SQL
Spark SQL enables users to run SQL/HQL queries. It allows us to process structured as well as semi-structured data. Also, Spark SQL offers to run unmodified queries up to 100 times faster on existing deployments.
Spark Streaming
One of the best things about Spark is that it enables a powerful interactive and data analytics application. What more, the live streams are converted into micro-batches that are executed on top of spark core.
Spark MLlib
Machine Learning library high-quality algorithms. Spark MLlib, one of the Apache Spark Tutorial components is highly recommended by data scientists. Moreover, Spark MLlib’s remarkable capacity of in-memory data processing optimizes the performance of the iterative algorithm.
Spark GraphX
Spark GraphX, another important spark tutorial component is a graph computation engine built on top of Apache Spark. It enables to process graph data at scale.
SparkR
SparkR is required to use Apache Spark from R. In more terms, we may say that it is an R package to ensure a light-weight frontend. Also, it is useful for analyzing large datasets and allows running jobs interactively on them from the R shell. The principal idea behind SparkR was to explore different techniques to integrate the usability of R with the scalability of Spark.
To know more about all the components of Spark in detail, you may look for online resources on Apache Spark Ecosystem.
Differences between Spark Tutorial and Adobe Spark Tutorial
Sometimes people confuse between Adobe Spark Tutorial and Apache Spark Tutorial. But let me tell you that the two products, though may sound similar (namesake, you may say) are as different from each other as chalk and cheese.
Apache Spark
Apache Spark Tutorial as you know is an open-source big data processing framework built around speed, ease of use, and sophisticated analytics.
It is fast gaining acceptance for its comprehensive, unified framework that manages big data processing requirements with diverse data sets. Moreover, with Apache Spark, you can write applications in Java, Scala, or Python. With a set of over 80 high-level operators, it can be used it interactively to query data within the shell.
Enrolling for Apache Spark tutorial will also show you it is better than other big data and MapReduce technologies like Hadoop and Storm.
Adobe Spark
With Adobe Spark you can create social graphics, web pages, and video stories anywhere for free. Moreover, Spark with its premium features is offered as part of Adobe Creative Cloud plan. It is also available as a stand-alone subscription, that is to say, you can customize the product according to your brand to create something unique.
You may take up an Adobe Spark Tutorial for a rewarding career in graphic designing. You will learn how to create stylish, effective social media posts. An Adobe Spark Tutorial also teaches you to use imagery that resonates with your target audience and works with your layout. It helps to answer your queries; how to use your brand’s colors in a way that creates an emotional connection; how to create branded templates that can save you time and money.
Spark Tutorial: Spark Tutorial Python
Python, one of the major programming languages, comes with a number of modules for interacting with the operating system, searching text with regular expressions, and accessing the Internet. The best thing about Python is that it is a dynamic, interpreted language that makes it unnecessary to declare variables or deal with memory management bugs, unlike what you do with C.
Python, combined with Apache Spark, makes it easier to process Big Data either in real-time or with scripts. The MapR distribution gives you everything you need to process Big Data in your favorite language.
Interested in a career in Python? Both beginners, as well as experienced programmers, can take up a Spark Tutorial Python, which will teach them how to use Python API bindings and gain knowledge on performing basic data analysis operations.
