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.

You specify nameservice and let Hadoop configuration take care of connecting to whatever the active namenode is. You don't have to worry about which namenode is active in your client code. By the way, you should use client side configuration files to connect to the cluster. You would specify the following in your hdfs-site.xml when you enable HA so you have a nameservice. dfs.nameservices dfs.ha.namenodes.[nameservice ID] dfs.namenode.rpc-address.[nameservice ID].[name node ID] or dfs.namenode.http-address.[nameservice ID].[name node ID] check the following link. https://hadoop.apache.org/docs/r2.7.2/hadoop-project-dist/hadoop-hdfs/HDFSHighAvailabilityWithNFS.html ...
