For “summary” command, I just pick the first carbondata file and read the schema from its header. The intention here is just to show one schema, assuming all schema in all data files in this folder is the same.
If there is need to validate schema in all files, we can add a “validate” command. It will be easy to add in CarbonCli tool I have raised PR2683 for this feature.
