Description

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.
