As Job Tracker knows the architecture with all steps that has to be followed in this way, it reduces the network traffic by streamlining the racks and their respective nodes. How Can You Categorize the Personal Data? Hadoop is an open-source framework that is designed for distributed storage and big data processing. Data are gathered to be analyzed to discover patterns and correlations that could not be initially apparent, but might be useful in making business decisions in an organization.
