Subject Re: Fwd: Sqoop export not working when using "update-key"
Date Mon, 12 May 2014 17:59:56 GMT
Hi Jarek,

thanks for replying, I don't have the logs. I'll see if I can run the task
again and then keep the logs.

Anyway, I don't remember seeing anything else than this SQLException about
missing parameter.
