Subject Re: hsqldb version problem

[Moving thread to cdh-user@cloudera.org as it seems to be CDH related +
bcc:user@hadoop.a.o]

Hi,

The underlying issue is that Sqoop depends upon HSQLDB 1.x whereas the
default jar bundled with CDH 4 is HSQLDB 2.x. Since this is bundled with
Hadoop for example purposes only, you should be able to carefully remove it
from the classpath and replace it with the previous version in order to get
past this problem.

Regards,
Arvind Prabhakar
