Describe the solution you'd like
In my implementation of the OtlpHttpSpanExporter, I want to access the http response status code and error message in case the export fails. Internally, the HttpExporter.export( ) method returns a CompletableResultCode response indicating successful or failed export and logs the status code and error message. I would like to know if it's possible to return this information from the exporter.

Describe alternatives you've considered
An alternative would be to write a custom exporter which returns all the required info.
