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';
