Subject Re: Export in free form And Mixed update/insert
Date Fri, 24 May 2013 05:06:41 GMT
Hi Jarek Jarcec Cecho

   Thanks for your response.

  I am sorry that the failed job because of the oraoop plugin which I add
before. Anyways I post the command and the log[1].

  The mixed update/insert job succeeds when I adopt the pure sqoop . Thanks
a  lot.
