> NULL values are passed to transformers as a literal backslash and a literal N. NULL values are saved when INSERT OVERWRITing LOCAL DIRECTORies as "NULL". This is inconsistent.
> The ROW FORMAT specification of tables should be able to specify the manner in which a null character is represented. ROW FORMAT NULL DEFINED AS '\N' or '\003' or whatever should apply to all instances of table export and saving.
