I've got 3 identical machines running centos networked to a main machine I'll use as a master node. Looking to install hadoop, spark, hive and probably zepplin. It's just for personal interest, might do some blogging etc of using it and running benchmarks and making hardware changes. Bit old school but it's interesting for me to repurpose some hardware that would otherwise end in the tip.

I was planning on using either Cloudera Distributed Hadoop (CDH) or Hortonworks Data Platform (HDP) but they require a license now. Do I just install the components separately? What about Ambari will that make things easier?
