[jira] [Created] (AVRO-2113) Improve unexpected type error message

Victor Mota created AVRO-2113:
---------------------------------

             Summary: Improve unexpected type error message
                 Key: AVRO-2113
                 URL: https://issues.apache.org/jira/browse/AVRO-2113
             Project: Avro
          Issue Type: Improvement
          Components: c++
            Reporter: Victor Mota
            Priority: Minor


Currently the error message for default type mismatch is not very user friendly:

https://github.com/apache/avro/blob/17f2d75132021fafeca29edbdcade40df960fdc9/lang/c%2B%2B/impl/Compiler.cc#L158
ie. "Unexpected type for default value: Expected 3, but found 2". Specifying the field where this is happening and what the types mismatched are in human readable format (ie. string, etc) would benefit the user a lot in debugging.
Here is an example of a user having issues understanding the error: https://issuetracker.google.com/issues/70351564.
