Subject CQL: fails to COPY <table> FROM <filename> with null values
Date Mon, 19 Jun 2017 14:10:15 GMT
 I am trying to copy a file of CSV data into a table
But I get an error since sometimes one of the columns (which is a UUID) is empty
Is this a bug or what am I missing?

Here is how it looks like
    id uuid,
    lastname text,
    firstname text,
    address_id uuid,
    dateofbirth timestamp,

PRIMARY KEY (id, lastname, firstname)

COPY playground.individual(id,lastname,firstname,address_id) FROM ‘testfile.csv’;

Where the testfile.csv is like this

This works !!!

This does NOT work !!!

Cause then I get the following error
Failed to import 1 rows: ParseError - badly formed hexadecimal UUID string,  given up without

So, how do I import my CSV file and set the columns which does not have a UUID to null ?
