Instance type required to deploy 4 node cluster of hadoop in aws

Question

To deploy a 4 node cluster of Hadoop in AWS which instance type can be used?

Answer 1

Hadoop cluster follows a master-slave concept. The master machine processes all the data, slave machines store the data and act as data nodes. Since all the storage happens at the slave, a higher capacity hard disk would be recommended and since master does all the processing, a higher RAM and a much better CPU is required. Therefore, you can select the configuration of your machine depending on your workload.
