> Join is broken after LOJoin patch (Optimizer_Phase5.patch of [PIG-697|https://issues.apache.org/jira/browse/PIG-697).
Even the simplest join script is not working under local mode:
> eg:
> a = load '1.txt';
> b = load '2.txt';
> c = join a by $0, b by $0;
> dump c;
> Caused by: java.lang.NullPointerException
