             Summary: Sqoop2: Generic JDBC connector is committing transaction on export with autoCommit on
                 Key: SQOOP-843
                 URL: https://issues.apache.org/jira/browse/SQOOP-843
             Project: Sqoop
          Issue Type: Bug
    Affects Versions: 1.99.1
            Reporter: Jarek Jarcec Cecho
            Assignee: Jarek Jarcec Cecho
             Fix For: 1.99.2


I've noticed that Generic JDBC Connector is not explicitly setting autoCommit and yet is committing transactions. This might lead to issues with for example MySQL JDBC driver that sets the autoCommit to true by default and calling commit will result in following exception being thrown:
