not sure if I understand your question. 4 data nodes, 2 masters and 1 edge looks fine. Namenode seem to have a lot of cores and memory. Data nodes look fine. What else is running on those name nodes that require 32 cores and 300 GB RAM? You didn't mention edge node configuration but that can be very flexible. normally I recommend 3 masters - 2 namenodes plus redundancy for everything including Hive metastore, Hiver Server 2, 3 zookeepers (with their own dedicate disks on each node), 3 quorum journal for namenode shared edits and fail over (2x500 GB SAS disks in RAID 1). So, ideally you want three masters.

Is that what your question is?

oh. If it's delivered by Teradata to you, then it's an appliance. If you bought your own hardware from let's say a vendor like HP, Dell or IBM then it's commodity - although term commodity hardware is not used anymore because people confuse it with personal laptops. A better term is "industry standard" hardware.

If you purchase a turnkey solution where everything came installed from the vendor like Teradata, then it's an appliance. If you bought your own hardware and then did an install and whole setup yourself, then it's industry standard hardware (aka commodity hardware).
