A big set of open-source programming tools called Apache Hadoop helps us use the computing power of several PCs to solve problems involving a lot of data and calculations. By providing a mechanism to distribute capacity, Hadoop Distributed File System (HDFS) will make it easier for end users to create the product. Its MapReduce program module will assist clients in processing massive amounts of data.
