Here is the error I'm getting on task tracker for the mapper:

Hopefully the above helps..
@Lars Francke
Thanks, I'll take a peek at those 2 patches.. But I've just recently
pulled down fresh code and recompiled everything and I'm still getting the
above error.
And for reference, below is my original email to the list.. Thanks all for you
help!

Hello All,
Has anyone been successful at running hive 0.11 with Cloudera CDH 4.3?
I've been able to get hive to connect to my metadb (which is in Postgres).
Verified by doing a show tables.. I can run explain and describes on tables,
but when I try to run anything that fires off an M/R job, I get the following
error:

I'm using my configs from hive 0.10, which works with no issues and this was
pretty much a drop in replacement on the machine that hadoop 0.10 was running
on..
I've done a bunch of googling around and have found a bunch of other folks that
have have had the same issue, but no solid answers..
Thanks in advance for any help..
