             Summary: Sqoop2: Generic JDBC: Prevent use of tableColumns and sql 
at the same time
                 Key: SQOOP-2445
                 URL: https://issues.apache.org/jira/browse/SQOOP-2445
             Project: Sqoop
          Issue Type: Sub-task
            Reporter: Jarek Jarcec Cecho
            Assignee: Jarek Jarcec Cecho
             Fix For: 1.99.7


We're supporting data retrieval with custom query. I see bunch of code around 
that is trying to solve situation when user enters both of custom query and 
specifies what columns he wants to transfer from that custom query. This seems 
to me as unnecessary complication as user can limit the column in the first 
place by specifying appropriate query. Hence I would like to prohibit this 
behavior.
