My understanding is that the purpose of the JSON-based infra for the errors classes is to put the content of all the error messages in one central human-readable place. This enables, for example, quick audit of all the error messages and their contents. As features, configs, etc. are added or retired, we can more easily tweak the messaging to guide the users towards or away from them. It also enables a translation layer to be implemented, so that the users can receive localized errors. Hard-coding extra information in Scala code hides it from the auditing and/or translation workflows. I am not sure what's the current policy in Spark, but in Delta - for the reasons mentioned above - we are trying to gradually eradicate any user-facing hard-coded error messages in Scala. -- This is an automated message from the Apache Git Service.
