             Summary: Sqoop2: Generic JDBC: Properly detect compound primary keys in GenericJdbcExecutor
                 Key: SQOOP-2443
                 URL: https://issues.apache.org/jira/browse/SQOOP-2443
             Project: Sqoop
          Issue Type: Sub-task
            Reporter: Jarek Jarcec Cecho
            Assignee: Jarek Jarcec Cecho
             Fix For: 1.99.7


[GenericJdbcExecutor.getPrimaryKey|https://github.com/apache/sqoop/blob/sqoop2/connector/connector-generic-jdbc/src/test/java/org/apache/sqoop/connector/jdbc/TestToInitializer.java#L195] currently returns the first column of the primary key. This works well if the table have one single column as PK, but won't work correctly when the table have compound key. I would like to return entire PK here and let the user of this method decides what to do (report error or use one of the columns of the key).
