      Description

      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.
