Sqoop >> mail # user >> Re: Hive Queries


[-user@hive, +user@sqoop]

Hi Cyrille,
this seems to me more a Sqoop issue than Hive issue, so I've moved this email to user@sqoop mailing list. I'm keeping user@hive in Bcc so that the mailing list will get the memo. Please join the user@sqoop mailing list [1] to receive additional feedback.

Exception that you're getting is typical when one is running code compiled against Hadoop 2.0 on Hadoop 1.0 or vice versa. You've specified that you're running Sqoop 1.4.2 --hadoop1.0.0.0, but that do not seem to be the case. Would you mind downloading it again from our mirror [2] and retrying it?
