So step 1 in understanding this Hadoop business is understanding clusters. Yes, Hadoop has one of the cutest logos in Big Data. And one of the rules when working with computers is that they always crash. Moreover, the more data you have stored in one server, the longer it takes to read through it to find the relevant information.
These issues first started preoccupying Google, whose business model is based on storing huge amounts of data and having access to all of it at one time. Makes sense. The basis of the system is to store the data on a cluster of servers. Instead of having to invest in a really large server, the system functions on the hard drives of lots of computers that you can compare to your PC. This system is infinitely scalable. MapReduce can take distributed data, transform it Map , and aggregate it Reduce into other useful data.
A node is a server by the way, which is basically a computer. I am grossly simplifying, but the driver node distributes jobs and tracks them across the worker nodes, which execute the jobs. Data is loaded into the client server when it is written by HDFS or processed by MapReduce, and then it is written on the worker nodes and YARN manages the resource allocation or the jobflow.
