The easiest way to start a Spark multi-node cluster in AWS is to use AWS EMR. There are various resources like this , which explain  how to Spark multi-node cluster.  But, EMR service does not support placement group.

The rest of the article will document the process. Disclaimer Most of the content of this document is from here  with some changes for example, the tutorial talks about install Spark on Ubuntu system and for our setup we wanted to use Centos (for legacy reasons). Steps 1. Spin N nodes on EC2. For this article, we assume N=5. Please make sure that the port...

How to access the VM from the host machine

This video clearly describes how to set this up.
