Using Hadoop to analyze big data for multiple purposes: An applied study according to the Map-Reduce model

The volume and diversity of data in the world are unprecedented in human history. It is growing at an unprecedented rate. Internet and social media technologies as they permeate every stage of our lives and even our mobile phones, people have become a source of data even in their daily activities. So, a new concept emerged: "Big Data". Big data is produced with high volume, speed, structured diversity, and semi-structured and unstructured data. Many industrial areas release big data by creating new data or digitizing existing data models so that organizations can gain a competitive advantage. In order to extract economic value from big data, it should be processed with advanced analytical methods. This research aims to examine the use of Hadoop in analyzing big data according to the Map-Reduce model. and distributed file systems such as Processing, PIG, Mahout, NoSQL, and Cassandra, and the study concluded that advanced analytical methods protect the privacy of personal information, and through them, security gaps can also be filled, and the phenomenon of big data was discussed in terms of its components and resources, and it was emphasized on the advantages of big data in the areas of application.
