    Attachment: SQOOP-2910.patch

Hi [~jarcec],

I've implemented the solution by using the apache hadoop cofiguration object, so now it's solved with not an argument but with a help of a -D property. I've created test cases for it, however I was not able to test it from CMD line. Could you please ensure that the testing is satisfying!

Thanks in advance!
Attila

> In the past several users faced issues when they tried to import String columns with the --split-by option. They didn't except to have any kind of issues/side effects, however this is a well known issue in Sqoop (and AFAIK we don't plan to change this behaviour).
> The objective here is to require the customer to explicitly choose to split by string which is known to have issues.
