In this blog, I will show you how to install Hadoop on a single node cluster. Considering the above example, in real-time when we deal with petabytes of data, it needs to be distributed across hundreds of machines to be processed.

The multi-node cluster is practically used in organizations for analyzing Big Data. While in a Multi-node cluster, there are more than one DataNode running and each DataNode is running on different machines. It can easily and efficiently test the sequential workflow in a smaller environment as compared to large environments which contain terabytes of data distributed across hundreds of machines.

So, for testing whether the Oozie jobs have scheduled all the processes like collecting, aggregating, storing, and processing the data in a proper sequence, we use a single node cluster. For example, let us consider a sample data set inside the healthcare industry. This is used for studying and testing purposes. Single node and Multi-node.Ī single node cluster means only one DataNode running and setting up all the NameNode, DataNode, ResourceManager, and NodeManager on a single machine. There are two ways to install Hadoop, i.e. The first step forward is to install Hadoop. I hope you would have liked our previous blog on HDFS Architecture, now I will take you through the practical knowledge about Hadoop and HDFS. You must have got a theoretical idea about Hadoop, HDFS and its architecture. But to get Hadoop Certified you need good hands-on knowledge.
