Good catch and fix [~jarcec]. Thanks for your contribution
> Oracle connector is not disabling autoCommit on created connections

> {{SqlManager}} will always [disable|https://github.com/apache/sqoop/blob/trunk/src/java/org/apache/sqoop/manager/SqlManager.java#L834]
the {{autoCommit}} in created connection and the rest of the Sqoop is written in a way that
it expects the {{autoCommit}} off by explicitly calling {{commit}} and {{rollback}} methods.
> Oracle connector currently [overrides|https://github.com/apache/sqoop/blob/trunk/src/java/org/apache/sqoop/manager/OracleManager.java#L278]
the method {{makeConnection}} without explicitly disabling the {{autoCommit}}. Depending on
the Oracle JDBC driver this might or might not be an issue as:
> * Version < 12.1 will allow calling {{commit}} and {{rollback}} on a connection that
have enabled {{autoCommit}}
> * Version >= 12.1 will *not* allow calling {{commit}} and {{rollback}} on a connection
that have enabled {{autoCommit}}. We've already seen this issue in the [user mailing list|http://mail-archives.apache.org/mod_mbox/sqoop-user/201309.mbox/%3C20130927160509.GB22393@localhost%3E].
> I believe that we should set the {{autoCommit}} in the Oracle connector to false in order
to make it compatible with Oracle JDBC driver version 12.1+ and also to make the connector
consistent with the rest of the code base.
