> 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.
