Hi Stephen,
Thank you for your reply. It was very helpful.
This weekend everything was working fine, but when I came back to the office,
the performance was slow again.
I checked the jobtracker and tasktracker and narrowed it down to; Shuffle
Error: Exceeded MAX_FAILED_UNIQUE_FETCHES; bailing-
Hi Jone,
um. i can say for sure something is wrong. :)
i would _start_ by going to the tasktracker. this is your friend. find
your job and look for failed reducers. That's the starting point anyway,
IMHO.

Hi,
I have tried some variations of queries with aggregation function such as the
following query;
select max(total) from my_table;
and
select id, sum(total) from my_table group by id
In my junit tests, I only have two rows with data, but the queries are
extremely slow.
The job detail outp
