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.
