I'm doing data load in a new environment and an export CSV didn't exist before I ran Add Entities to populate it. Since the file didn't exist the connector is failing the entity adds and the log file is now filling with one error for each entity, which has made the system unusable for over 5 minutes. If I had more like 100,000 records to write out this could delay the data load activity for an hour or more.
While not a show-stopper (I've now created a CSV file with headers and no data and re-run the Add Entities operation) it's annoying and I don't see why the file can't simply be created if it doesn't exist.
