-------------------------
Hi
I'm tying to run the mapreduce version of the ranking_select job of the
hive-benchmarks, and I'm getting a java error (see below).
I thought that the error comes from the ranking data but the
rankings_uservisits_join job runs without any problem.
Any help would be appreciated.
