-Re: How to Use AvroStorage to read avro data and convert into a new (compatible) schema
Try loading the data in schema one, and storing it/transforming it in
schema two in a new location?
Then try to load it, and see what it is. This may not be feasible if
your data is large, but worth a try to help debug?
