Apache Spark is a powerful open-source monitoring and distributed general-purpose in-memory computing engine which is written in the Scala programming language. Apache Spark and Scala provide fault-tolerant in-memory data parallelism at a very fast, standard interface and ease of use. Most of the big data developers choosing Scala programming language in the Apache Spark framework to build big data applications with faster data analysis.
Scope of Apache Spark and Scala is immense because of its demandable key features like less complexity, fast memory computations, dynamic programming, inbuilt machine learning libraries, data streaming, real-time analysis, graphs libraries, high productivity, and performance.

Apache Spark is an open-source cluster computing framework that was initially developed at UC Berkeley in the AMPLab.As compared to the disk-based, two-stage MapReduce of Hadoop, Spark provides up to 100 times faster performance for a few applications with in-memory primitives. Scala is a modern and multi-paradigm programming language. It has been designed for expressing general programming patterns in an elegant, precise, and type-safe way. One of the prime features is that it integrates the features of both object-oriented and functional languages smoothly.
Although there are many spark classroom training Portals. Hachion is one of the best Spark classroom training Institutes, with the expert instructors who provide great support at the time of learning. As the course, is all about learning to manage and process volumes of data, it is recommended for those who work upon managing big data. Also, for the matter of fact that, Apache spark technology is the foundation to understand the architecture and functionalities of software technology like big data.
Hachion's Spark & Scala training program covers from basic to advanced concepts in Spark and Scala. Our course curriculum is designed by industry experts in the IT industry. We provide 100% job assistance with certification guidance.
