Hadoop clusters are particularly known for boosting the speed of data analysis applications and their scalability. If at any point a cluster’s processing power is under stress by the growing volumes of data, it can be dealt by adding additional cluster nodes to increase throughput. Hadoop clusters have high resistance to failure because each block of data is copied onto other nodes ensuring that the data is not lost if a single node fails.

I have implemented this to my network following link below instructions:
