According to the cluster documentation, you can either define data nodes with:





I don't see a substantial difference between the two. The documentation has this to say:

The [computer] section has no real significance other than serving as a way to avoid the need of defining host names for each node in the system.

I'm stumped. If I have to define a hostname, what benefit is there to defining it in [computer] instead of [ndbd]?

Its more a matter of convenience and clarity I would say. For example if you are referring the same HostName in multiple places in the config file, its better to define it under [computer] section and use the corresponding Id in [ndbd] sections. Also, if in case you have to change the HostName in the future, you would just have to change it under the [computer] section.
