You can refer below as a reference or if you plan to use custom ports then make sure are they are allowed via firewall. If you have firewall between servers then make sure all the Hadoop service ports are open.JDK installed on all the nodes – I used jdk-8u151.DNS – Both forward and reverse lookup enabled.3x Hadoop DataNodes – 6GB RAM and 4vCPU.3x Yarn ResourceManager nodes – 4GB RAM and 2vCPU.2x Hadoop NameNodes – 4GB RAM and 2vCPU.CentOS x86_64_-Minimal for all the nodes.Hortonworks Hadoop Cluster Planning Guide To complete this article, you will need below Infrastructure: I have build this infrastructure for lab, however if you plan to build for production please refer to the Hadoop documentation for hardware recommendations: Below is for Hortonworks Hadoop cluster is running on Openstack.All the nodes in the cluster are Virtual Machines.
