Kaushik says that the average Hadoop cluster size reflects follows a fairly predictable curve. Our observation is that companies typically experiment with cluster size of under 100 nodes and expand to 200 or more nodes in the production stages. Some of the advanced adopters cluster sizes are over 1,000 nodes..
It most probably doesn't matter, if you are just running hadoop out of the box on your single-node-cluster or even a small personal distributed cluster. You just need to worry about memory. Long Answer. vCores are used for larger clusters in order to limit CPU for different users or applications. If you are using YARN for yourself there is no real reason to limit your container CPU. That is why vCores are not even taken into consideration by default in Hadoop ! Try setting your available nodemanager vcores to 1.
