Hi Dean,

I'm running everything on a single physical machine in pseudo-distributed mode.

Well it certainly looks like the reducer is looking for a derby.jar, although I 
must
confess I don't really understand why it would be doing that.
In an effort to fix that I copied the derby.jar (derby-10.4.2.0.jar) into the
Hadoop directory, where I assume that the reducer would be able to find it.
However I get exactly the same problem as before.
Is there some particular place that I should put the derby.jar to make this
problem go away? Is there anything else that I can try?

It looks like you're using Derby with a real cluster, not just a single machine 
in local or pseudo-distributed mode. I haven't tried this myself, but the derby 
jar is probably not on the machine that ran the reducer task that failed.

Hi Shreepadma,

I agree that the error looks odd. However I can't believe that I would have
got this far with Hive if there was no derby jar. Nevertheless I checked.
Here is a directory listing of the Hive install:
