    Description

      Most of the SkewedJoin tests fail.

      a = load '/user/user1/pig/tests/data/singlefile/studenttab10k' using PigStorage() as (name, age, gpa);
      b = load '/user/user1/pig/tests/data/singlefile/votertab10k' as (name, age, registration, contributions);
      e = join a by name, b by name using 'skewed' parallel 8;
      store e into '/user/user1/pig/out/user1.1321044742/SkewedJoin_1.out';
