I'm trying to install Apache Hadoop 2.2.0 on my MacOS as single-node cluster and unable to find any documentation which helps to complete setup without errors. All guidelines I found so far on Hadoop, Cloudera and other web sites are either lack details or contain outdated information. Can anyone refer to consistent and clean step-by-step instruction which really works for single-node Apache Hadoop 2.2.0 setup on MacOS ?

Single Node Cluster – It Has one DataNode running and setting up all the NameNode, DataNode, Resource Manager, and NodeManager on a single machine. This is used for studying and testing purposes. Multi-Node Cluster – Has more than one DataNode running and each DataNode is running on different machines.
A Multi Node Cluster in Hadoop contains two or more DataNodes in a distributed Hadoop environment. This is practically used in organizations to store and analyze their Petabytes and Exabytes of data. Learning to set up a multi node cluster gears you closer to your much needed Hadoop certification.
I recently wrote a guide of my own as I also found the official documentation lacking and because all other guides seem to be stuck on the pre-YARN hadoop mentality and are full of no longer necessary steps/environment values. I also included a Fabric script for easy cluster deployment. I would love your feedback!
