The core of Apache Hadoop consists of a storage part, known as Hadoop Distributed File System (HDFS), and a processing part which is a MapReduce programming model.Hadoop splits files into large blocks and distributes them across nodes in a cluster. It then transfers packaged code into nodes to process the data in parallel.

Before Hadoop the data was stored in traditional data storage system i.e., RDBMS. But RDBMS could store only structured data which added limitations to its efficiency. The vast scale unstructured data couldn't be stored in RDBMS. So, Hadoop emerged as a solution to this problem. HDFS which is Hadoop's storage layer can reliably store any kind of data on massive scale. It is helpful for the storage of increasing data.

Hadoop is the most popular tool to manage big data. It provides distributed storage (using HDFS) and parallel data processing (using Map Reduce). Hadoop is an ecosystem which consists open source components. Hadoop helps many organizations to store, analyze and process the data in a better manner.
