Systems like Apache Spark [8] have gained enormous traction thanks to their intuitive APIs and abil-ity to scale to very large data sizes, thereby commoditiz-ing petabyte-scale (PB) data processing for large num-bers of users. Web-based companies like Chinese search engine Baidu, e-commerce opera-tion Alibaba Taobao, and social networking company Tencent all run Spark- Written in Scala language (a ‘Java’ like, executed in Java VM) Apache Spark is built by a wide set of developers from over 50 companies. Moreover, we will also learn about the components of Spark run time architecture like the Spark driver, cluster manager & Spark executors. Read: HBase Interview Questions And Answers Spark Features. Apache Spark has a well-defined layer architecture which is designed on two main abstractions: The Apache Spark framework uses a master–slave architecture that consists of a driver, which runs as a master node, and many executors that run across as worker nodes in the cluster. In this blog, I will give you a brief insight on Spark Architecture and the fundamentals that underlie Spark Architecture.
