  • 11. Who is a Data Scientist? Data science incorporates varying elements and builds on techniques and theories from many fields, including mathematics, statistics, data engineering, pattern recognition and learning, advanced computing, visualization, uncertainty modeling, data warehousing, and high performance computing with the goal of extracting meaning from data and creating data products. A practitioner of data science is called a data scientist

  • 19. MapReduce & HDFS • MapReduce is a programming model for processing large data sets with a parallel, distributed algorithm on a cluster (a group of connected computers that work together so that in many respects they can be viewed as a single system) • A MapReduce program comprises a Map() procedure that performs filtering & sorting and a Reduce() procedure that performs a summary operation. • The "MapReduce System" orchestrates by marshaling the distributed servers, running the various tasks in parallel, managing all communications and data transfers between the various parts of the system, providing for redundancy and fault tolerance, and overall management of the whole process. • HDFS is a distributed, scalable, and portable file system written in Java for the Hadoop framework.
  • 20. Hadoop • Apache Hadoop is an open-source software framework that supports data-intensive distributed applications, licensed under the Apache v2 license. • Effectively, it implements MapReduce & provides a distributed file system (HDFS) • It supports the running of applications on large clusters of commodity hardware. • Hadoop makes it possible to run applications on systems with thousands of nodes involving thousands of terabytes. Its distributed file system facilitates rapid data transfer rates among nodes and allows the system to continue operating uninterrupted in case of a node failure. This approach lowers the risk of catastrophic system failure, even if a significant number of nodes become inoperative.
