Power Supplies: Hadoop software is designed around the expectation that nodes will fail. Redundant hot-swap power supplies are not necessary for worker nodes, but should be used for master, utility, and edge nodes. If using single power supplies on worker nodes, confer with your data center team to alternate the power feeds for each rack. For example, Rack 1 goes on Feed A, Rack 2 goes on Feed B, Rack 3 goes on Feed C, repeating the pattern.
