From time to time I have a csv file coming with single row and it breaks the Glue Crawler because of the at least 2 row requirement to be classified as a CSV.
Is there a way I can provide a custom CSV classifier so I don't need to write a grok for 300+ columns? I can't seem to be able to figure out what to use in Quote symbol since I don't have any quotes in the csv.
This is a snippet of the data:
SSR|CCE|34|BBB||1
I can write something like this
(?<col0>^.*)(?:[^|]*\|)
as a grok and repeat 300 times but would be good to make it less ugly
