Expected Behavior
If key column is the same as the value column, the csv data adapter can be used as a check whether a given key exists in the file. If that is not desired by the Graylog developers, the UI should prohibit setting the key column and the value column the same.
Current Behavior
Currently, if the key column and the value column are the same in the CSV data adapter, Graylog throws a null pointer exception in the server log file.
