-----------------------------------

             Summary: Add capability to Sqoop to require an explicit option to 
be specified with --split-by for a String column
                 Key: SQOOP-2910
                 URL: https://issues.apache.org/jira/browse/SQOOP-2910
             Project: Sqoop
          Issue Type: Improvement
            Reporter: Attila Szabo


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.

--split-by <CHAR_COLUMN> --i-know-what-i-am-doing
