> -------------------------------
>
> Key: PIG-4189
> URL: https://issues.apache.org/jira/browse/PIG-4189
> Project: Pig
> Issue Type: Sub-task
> Components: spark
> Reporter: Praveen Rachabattuni

> Related e2e tests: Cross_1 - Cross_5
> Sample script:
> a = load '/user/pig/tests/data/singlefile/studenttab10k' as (name, age, gpa);
> b = load '/user/pig/tests/data/singlefile/votertab10k' as (name, age,
> registration, contributions);
> c = filter a by age < 19 and gpa < 1.0;
> d = filter b by age < 19;
> e = cross c, d;
> store e into '/user/pig/out/praveenr-1411378727-nightly.conf/Cross_1.out';
